Leak detection work rarely announces in advance whether it’s an indoor job or an outdoor one. A call-out for “water coming from somewhere near the bathroom” might turn out to be a slab leak that’s tracked outside the building line. A high water bill investigation that starts at the meter might end up needing a wall cavity check once you’ve traced the line back into the house. For technicians who only carry indoor or only carry outdoor equipment, that kind of job means either turning up under-equipped or making a second trip — neither of which does much for your day rate or your client’s confidence.

The alternative — owning two separate leak detection kits — solves the coverage problem but creates a logistics one. Two units to charge, two cases to carry, two sets of consumables to track, and inevitably the one job that needs the kit currently sitting back at the workshop. For contractors and utility teams whose work spans both indoor plumbing and outdoor service lines as a matter of course, that’s an ongoing tax on every job, not just an occasional inconvenience.

One main unit, two purpose-built sensors

The HIKMICRO AD22P-I/O solves this by combining both sensor types into a single kit built around the same AD22P main unit and 7″ touchscreen used across the range. You get the high-sensitivity indoor sensor for wall, floor, ceiling, and underfloor heating leak detection, and the IP66-rated outdoor sensor for ground-contact detection of buried service lines, courtyards, and paved areas — plus listening sticks for fast, direct-contact checks on exposed pipework and fittings.

The unit auto-recognises whichever sensor is connected, so moving from an indoor wall check to an outdoor ground survey on the same job doesn’t involve any manual reconfiguration — unplug the indoor sensor, connect the outdoor sensor, and the AD22P-I/O adjusts its filtering and mode options accordingly. That matters on jobs where you genuinely don’t know at the outset whether the leak is going to end up being an indoor or outdoor problem, or where it turns out to be both.

Frequency coverage tuned for both environments

Indoor and outdoor leaks produce sound in meaningfully different frequency ranges, which is why the AD22P-I/O gives you dedicated presets for each rather than one generic setting stretched across both jobs. Indoor Mode 1 (5,000–16,000 Hz) and Indoor Mode 2 (8,000–16,000 Hz) are tuned for the higher-frequency sound typical of leaks travelling through building structure, while Outdoor Mode (200–2,000 Hz) is tuned to the lower-frequency signature of water escaping underground. Custom Mode extends across the instrument’s full 200–16,000 Hz range for the leaks that don’t sit neatly in either preset — whatever the pipe material, burial depth, or building construction throws at you.

SuperDetect, HIKMICRO’s automated leak-zone analysis feature, operates in indoor mode to highlight probable leak locations directly on the touchscreen — a genuine time-saver on indoor jobs, and one more reason the combo kit earns its place over carrying a basic listening-only tool for indoor work.

Two inspection workflows, whichever environment you’re in

The AD22P-I/O carries the same two inspection modes across both sensor types. Quick Inspection Mode supports fast, comparative screening — walk a suspected area, compare relative sound levels at a series of points, and narrow things down quickly, whether that’s a room inside a building or a stretch of paving outside it. Route Inspection Mode supports a more structured, multi-point survey for larger or more complex investigations, useful on bigger commercial properties or longer buried service runs where a quick scan alone won’t give you the confidence to commit to a cut or a dig point.

Being able to apply the same locate → localise → pinpoint workflow regardless of whether you’re indoors or outdoors means less mental context-switching between tools and more consistency in how you document and report findings.

Everything in one case

The AD22P-I/O kit includes the AD22P main unit, the indoor sensor, the outdoor sensor, listening sticks, a headset, and a hard carry case to keep the full kit organised and protected in transit. It’s genuinely built as a single, complete solution rather than a bundle of two separate product lines — one case to grab off the shelf before a job, regardless of what that job turns out to need.

A full day’s work, indoors or out

Battery performance doesn’t change based on which sensor is attached — the AD22P-I/O runs up to 11 hours continuously on its rechargeable Li-ion battery, with a 4-hour recharge time, whether you’re spending the morning inside a building and the afternoon tracing a service line outside it. Audio findings are saved in .wav format for review on PC, and image captures in .jpeg for documentation, with USB 2.0 (USB Type-C) connectivity for pulling data across for reporting once you’re back at the office.

Who the combo kit makes sense for

Full-service leak detection contractors who don’t want to turn down a job because it’s the “wrong” kit day. Plumbing companies fielding a mix of indoor plumbing call-outs and outdoor water-bill investigations from the same client base. Water utility contractors whose work regularly spans from the meter, along the service line, and into the building. Facility management teams responsible for both the building envelope and the surrounding grounds, where a leak investigation might legitimately need to go either way depending on where it leads. In every case, the value of the AD22P-I/O isn’t just having both sensors — it’s not having to predict, before you arrive on site, which one you’re going to need.

Backed by local support that understands the trade

We stock and support the full HIKMICRO acoustic leak detection range for Australian trade professionals, including advice on which kit configuration fits your actual job mix. If most of your work is squarely indoor or squarely outdoor, the dedicated AD22P-I or AD22P-O kit may be the more cost-effective choice — we’re happy to talk through the difference so you’re not paying for sensor coverage you won’t use. For contractors genuinely working across both environments, the AD22P-I/O is built to be the only leak detection kit you need to carry.

Technical Specifications

What is the HIKMICRO AD22P-I/O used for? The AD22P-I/O is a combined acoustic leak detector kit that includes both an indoor sensor and an IP66-rated outdoor sensor, allowing technicians to investigate leaks inside a building and in outdoor service lines or paved areas using a single device.

Why choose the AD22P-I/O over the separate indoor or outdoor kits? The combo kit removes the need to predict, before arriving on site, whether a job will end up being an indoor or outdoor leak investigation — both sensors are included, and the unit auto-recognises whichever one is connected.

Does the AD22P-I/O sacrifice anything compared to the dedicated indoor or outdoor kits? No — it uses the same main unit, the same indoor and outdoor sensors, and the same frequency ranges, inspection modes, and SuperDetect functionality found in the individual AD22P-I and AD22P-O kits, combined into one kit.

How does sensor switching work on the AD22P-I/O? The device auto-recognises which sensor is physically connected — indoor or outdoor — and adjusts its available filter presets and modes accordingly, with no manual configuration required.

Can the AD22P-I/O detect both a wall-cavity leak and a buried service line leak on the same job? Yes — that’s the specific scenario this kit is designed for, using the indoor sensor for the building-envelope portion of the investigation and the outdoor sensor for the buried or exterior portion.

How long does the AD22P-I/O run on a single charge? Up to 11 hours of continuous operation from its rechargeable Li-ion battery, with a 4-hour recharge time, regardless of which sensor is in use.

Who is the AD22P-I/O best suited for? Full-service leak detection contractors, plumbing companies, and water utility field teams whose work regularly spans both indoor plumbing investigations and outdoor property-side or service line leak detection.

A leak in an outdoor service line rarely shows itself the way an indoor drip does. There’s no ceiling stain, no puddle under the sink — just water quietly disappearing into the ground under a driveway, a courtyard, or a stretch of buried pipe between the meter and the building. Often the first sign is a water bill that doesn’t add up, a damp patch appearing in an otherwise dry garden bed, or a section of paving that’s started to subside. By the time any of that is visible, the leak has usually been running for a while, and the water authority or property owner wants an answer fast: where, exactly, do we dig?

Digging blind is expensive and disruptive. Break up the wrong section of concrete, trench through the wrong garden bed, and you’ve added a repair bill on top of the leak itself — plus a client who’s now watching every move you make on the rest of the job. For contractors working property-side leak detection, plumbing companies fielding high water bill call-outs, or civil teams investigating service line loss, pinpoint accuracy before the shovel comes out isn’t a nice-to-have, it’s the entire value proposition.

Purpose-built for ground contact, not adapted from an indoor tool

The HIKMICRO AD22P-O pairs the AD22P main unit with an outdoor sensor engineered specifically for ground-contact use — a meaningfully different job to picking up sound through a plasterboard wall. Water escaping under pressure from a buried pipe generates low-frequency sound that travels through soil, paving, and pipe material before it reaches the surface, and the AD22P-O’s outdoor sensor and Outdoor Mode band-pass filter (200–2,000 Hz) are tuned to that lower frequency range specifically, rather than trying to stretch an indoor-tuned sensor to cover a job it wasn’t built for.

The kit also includes listening sticks — a more traditional, direct-contact method of picking up sound from valves, hydrants, and exposed pipe sections, useful for narrowing down a search area before committing to ground-sensor placement, or for jobs where a quick manual check is faster than setting up the full acoustic survey. Having both tools in one kit means you’re not carrying separate equipment for different stages of the same investigation.

Like the rest of the AD22P range, the AD22P-O auto-recognises which sensor is connected, so switching between the outdoor ground sensor and listening sticks on site doesn’t require digging through a menu — attach the sensor and the unit configures itself accordingly.

From general area to exact point

Outdoor leak jobs typically move through a broader search before narrowing down, and the AD22P-O’s two inspection modes reflect that. Quick Inspection Mode is built for walking a suspected stretch of pipe run or paved area and comparing relative sound levels at a series of points to rule areas in or out fast — useful when you’re trying to establish which side of a property boundary a leak sits on, or which section of a long service run is affected. Route Inspection Mode supports a more structured, multi-point walkthrough for longer runs or larger properties, building a clearer sound-intensity picture across the whole suspected area before committing to a dig point.

That locate → localise → pinpoint workflow matters more outdoors than almost anywhere else, because the cost of being wrong is measured in metres of unnecessary excavation, not just a patch-and-repaint job.

Custom Mode for the leaks that don’t play by the rules

Not every outdoor leak sits neatly in the 200–2,000 Hz Outdoor Mode band — pipe material, burial depth, soil type, and pressure all shift the acoustic signature. The AD22P-O’s Custom Mode lets you adjust anywhere across the instrument’s full 200–16,000 Hz range, so if a job’s producing a signal outside the standard outdoor preset, you’re not stuck guessing — you can tune the filter to match what you’re actually hearing.

What’s in the outdoor kit, specifically

The AD22P-O is built around outdoor property-side work: the AD22P main unit and its 7″ touchscreen, the dedicated ground-contact outdoor sensor, listening sticks for direct-contact checks, a headset for clear monitoring in noisy outdoor conditions (traffic, wind, nearby equipment), and a hard carry case to keep the kit protected between sites. It doesn’t include the high-sensitivity indoor sensor that ships with the AD22P-I — if your work also takes you inside the building envelope regularly, the combined AD22P-I/O kit covers both scenarios with a single device rather than requiring two separate kits.

Rated to work a full day outdoors

Field jobs run long, and the AD22P-O carries the same 11-hour continuous battery life and 4-hour recharge as the rest of the AD22P range, so a full day of property surveys or a multi-site route doesn’t mean carrying a spare battery or hunting for a power point. Audio and image data are stored on-device — audio in .wav format for review on PC, images in .jpeg for documentation — with USB 2.0 (USB Type-C) connectivity for transferring findings back to the office for reporting or client sign-off.

Who this kit is built for

Plumbing and leak detection contractors responding to unexplained high water bills on residential or commercial properties. Water utility field teams and contractors investigating service line loss between the meter and the property boundary. Civil and irrigation contractors tracking leaks in buried supply lines across larger sites. Facility and grounds maintenance teams responsible for outdoor infrastructure at commercial or institutional properties, where an undetected leak can undermine paving, erode garden beds, or waste significant volumes of water over time.

Backed by local trade support

We supply and support HIKMICRO’s acoustic leak detection equipment for Australian trade professionals, which means you get advice on the right kit for the work you actually do, ready access to accessories, and after-sales support from a team that understands test and measurement gear. If you’re not sure whether the outdoor-only AD22P-O or the combined AD22P-I/O kit is the better fit, we’re happy to talk through your typical job mix.

Technical Specifications

What is the HIKMICRO AD22P-O used for? The AD22P-O is an acoustic leak detector configured for outdoor, property-side water leak detection — locating leaks in buried service lines, under paving, and across courtyards or garden areas outside the building envelope.

Why does the AD22P-O use a different sensor to the indoor AD22P-I? Underground leak sound travels differently to indoor leak sound — it’s typically lower frequency and needs to be picked up through ground contact rather than through a wall or floor, which is why the AD22P-O ships with a dedicated outdoor sensor rated IP66 and an Outdoor Mode filter tuned to 200–2,000 Hz.

What’s included in the AD22P-O kit that isn’t in the AD22P-I kit? The AD22P-O includes the outdoor ground-contact sensor and listening sticks, in place of the AD22P-I’s indoor sensor. Technicians who need both are better served by the combined AD22P-I/O kit.

Can the AD22P-O be used to trace leaks in buried water service lines? Yes — that’s the core use case for this configuration, using the outdoor sensor’s ground-contact detection alongside listening sticks for exposed valves and pipe sections.

How rugged is the AD22P-O outdoor sensor? The outdoor sensor carries an IP66 rating, providing dust-tight and high-pressure water jet protection suited to ground contact and outdoor field conditions.

How long does the AD22P-O run before needing a recharge? Up to 11 hours of continuous operation from its rechargeable Li-ion battery, with a 4-hour recharge time.

What are listening sticks used for on the AD22P-O? Listening sticks provide a direct-contact way to pick up sound from valves, hydrants, and exposed pipework, useful for narrowing a search area quickly before or alongside a full ground-sensor survey.

A dripping tap is easy. A leak behind a bathroom wall, under a slab, or inside a hydronic heating loop is a different job altogether. By the time a ceiling stain, a spike in the water bill, or a damp patch on the carpet gives the game away, water may have been tracking through a wall cavity or under a floor for weeks. Every hour spent guessing at a leak location is an hour of potential water damage, mould growth, and an increasingly frustrated homeowner or facility manager standing over your shoulder.

The traditional fallback — invasive investigation — means cutting into plasterboard, lifting tiles, or trenching a slab on a hunch. Get it wrong and you’ve created a repair bill on top of the original problem, plus a client who’s now questioning your judgement. For technicians working across strata properties, aged care facilities, or commercial fitouts, that kind of exploratory damage isn’t just costly, it’s often not an option at all.

How the AD22P-I earns its keep

The HIKMICRO AD22P-I is built specifically to answer one question with confidence: where, exactly, is this leak? It does that by listening rather than guessing. Pressurised water escaping through even a hairline crack in a pipe generates a distinct acoustic signature — a hiss or turbulent flow noise that travels through pipework, concrete, and building structure. The AD22P-I’s indoor sensor is tuned to pick up that signature through walls, floors, and ceilings, while the main unit’s processing does the work of separating leak noise from the ambient racket of an occupied building — foot traffic, HVAC systems, appliances, road noise from outside.

What sets this unit apart from a basic listening stick is HIKMICRO’s SuperDetect function. Rather than relying purely on trained ears and years of field experience, SuperDetect analyses the captured acoustic data and highlights the areas most likely to contain the leak directly on the 7″ touchscreen. It’s not a replacement for technician judgement — it’s a second opinion that helps newer techs get up to speed faster and helps experienced techs move through a job with more certainty and less second-guessing.

The AD22P-I also gives you control over exactly what frequency range you’re listening to, which matters more than it sounds. Different leak scenarios — a slab leak, a wall-cavity leak, an underfloor heating pipe — produce sound at different frequencies depending on pipe material, water pressure, and what the sound has to travel through before it reaches the sensor. Indoor Mode 1 (5,000–16,000 Hz) and Indoor Mode 2 (8,000–16,000 Hz) give you two pre-set bands tuned for typical indoor scenarios, while Custom Mode lets you dial in anywhere from 200 to 16,000 Hz if a job needs something more specific. That flexibility means you’re not fighting the instrument to get a clean signal — you’re tuning it to the job in front of you.

Two ways to work a job

Every leak investigation doesn’t follow the same pattern, so the AD22P-I supports two inspection workflows. Quick Inspection Mode is built for rapid comparison — walk the suspected area, compare relative sound intensity at a handful of points, and narrow down a general zone fast. That’s the mode you reach for when a facilities manager wants an answer before lunch and the leak is reasonably contained to one section of a building.

Route Inspection Mode is the more methodical option: a structured, multi-point walkthrough that builds a clearer picture across a wider area before you commit to a pinpoint location. It’s the better fit for larger commercial fitouts, multi-unit residential buildings, or any job where getting it wrong the first time means a second, more awkward conversation with the client about why the wall’s been opened up twice.

Locate, localise, pinpoint — that’s the practical workflow this device is designed around, and having both inspection modes available means you’re not forcing every job through the same process.

What’s actually in the box, and why it matters for indoor work

The AD22P-I kit is built around indoor scenarios specifically — it isn’t trying to be everything to everyone. You get the AD22P main unit with its 7″ touchscreen, the dedicated high-sensitivity indoor sensor, a headset for clear audio monitoring in noisy environments, and a hard carry case to keep the kit protected and organised between jobs. The unit auto-recognises the connected sensor, so there’s no manual configuration step slowing you down on site — attach the indoor sensor and the AD22P-I is ready to work.

Because this is the indoor-specific kit, it doesn’t include the outdoor ground-contact sensor or listening sticks that come with HIKMICRO’s outdoor and combo kits. If your work regularly takes you outside the building envelope — service lines, courtyards, paved areas — the AD22P-O or the combined AD22P-I/O kit will cover that ground as well. For technicians whose leak detection work is squarely indoor plumbing, wall, floor, and underfloor heating investigation, the AD22P-I is the more focused, better-value option.

Built for a full day on site

Battery life matters when you’re moving between jobs or working through a large commercial floor plate, and the AD22P-I is rated for up to 11 hours of continuous operation from its rechargeable Li-ion battery, with a 4-hour charge time when you do need to top it up. Audio findings are stored on the device and image captures can be saved directly for reporting, with the touchscreen giving you a straightforward way to review captured data on site before you finalise a diagnosis. Data connects out via USB 2.0 (USB Type-C), making it simple to pull captured audio and images across to a PC for closer review, documentation, or client reporting via HIKMICRO’s companion software.

Who reaches for the AD22P-I

Plumbing contractors chasing intermittent leaks in occupied homes, where cutting into the wrong wall isn’t an option. Facility managers and body corporate maintenance teams responsible for aged buildings with ageing copper or PEX runs behind finished surfaces. Hydronic heating specialists needing to trace a leak in an underfloor loop without lifting an entire floor. Insurance assessors and building inspectors who need to document leak location and extent as part of a claim or condition report. In each case, the value isn’t just finding the leak — it’s finding it with enough confidence to justify where you’re about to cut, drill, or dig.

Why source it through us

We stock and support HIKMICRO’s acoustic leak detection range specifically for Australian trade professionals, which means local advice on which kit configuration actually suits your work, straightforward access to accessories and consumables, and after-sales support from people who understand test and measurement equipment rather than a generic electronics retailer. If you’re weighing up the AD22P-I against the outdoor or combo kit, we’re happy to talk through which one matches the jobs you’re actually doing.

Technical Specifications

What is the HIKMICRO AD22P-I used for? The AD22P-I is an acoustic leak detector built for locating hidden water leaks inside buildings — behind walls, under floors, and within underfloor heating pipework — without needing to cut into finishes to find the source first.

How does the AD22P-I find a leak without seeing it? It listens for the acoustic signature that pressurised water makes as it escapes through a crack or joint, using a dedicated indoor sensor and adjustable band-pass filters to isolate that sound from general building noise, then uses SuperDetect to highlight the most likely leak zone on-screen.

What’s the difference between the AD22P-I and the AD22P-O? The AD22P-I is fitted out for indoor work with a high-sensitivity indoor sensor, while the AD22P-O is configured for outdoor, ground-contact leak detection with an outdoor sensor and listening sticks. The AD22P-I/O combo kit includes both sensor types for technicians who need to cover indoor and outdoor scenarios with one device.

Can the AD22P-I detect leaks in underfloor heating pipes? Yes — underfloor heating loops are one of the harder indoor leak scenarios to diagnose without invasive investigation, and it’s a typical use case for the indoor sensor and SuperDetect combination.

How long does the AD22P-I run on a single charge? The unit is rated for up to 11 hours of continuous operation from its rechargeable Li-ion battery, with a 4-hour recharge time.

Does the AD22P-I require training to use effectively? It’s designed to be usable by both new and experienced technicians — SuperDetect assists less experienced users by highlighting likely leak zones, while the manual amplification and custom frequency mode give experienced technicians full control when they want it.

What inspection workflows does the AD22P-I support? Two modes: Quick Inspection Mode for fast, comparative screening of a suspected area, and Route Inspection Mode for structured, multi-point investigation across a wider space.
