Insulation resistance testing is non-negotiable. Whether you’re commissioning a new installation under AS/NZS 3000, verifying a solar array to AS/NZS 5033 and IEC 62446-1, or running scheduled maintenance on industrial switchboards, you have to prove the insulation holds up. The trouble is, traditional insulation testers can be painfully slow — waiting for readings to settle, manually transcribing results onto paper, then re-keying everything into a report back at the office.

For a time-poor sparkie or solar tech doing dozens of tests a day, those wasted seconds and double-handled data points add up to real money and real risk. Transcription errors creep into compliance documents. Test certificates get delayed. And when a client or auditor asks for evidence, you’re digging through a clipboard instead of pulling a clean digital record.

The Solution: Speed, Range and Wireless Reporting in One Handheld

The KYORITSU KEW 3552BT was engineered to strip the friction out of insulation and continuity testing. At its core is a measurement engine delivering world’s-fastest-class measurement speed of just 0.5 seconds — so you spend less time waiting at the probes and more time moving through the job.

It covers six selectable insulation test voltages — 50V, 100V, 125V, 250V, 500V and 1000V — making it equally at home on low-voltage control circuits, standard 230V domestic and commercial wiring, and higher-voltage solar PV strings. The 1000V range pushes insulation resistance measurement up to 40GΩ, giving you the headroom needed for serious PV and industrial work.

Where the 3552BT really earns its keep is data. The “BT” model adds Bluetooth 5.0 wireless communication and internal memory, so every reading can be saved on the instrument and pushed straight to your phone or tablet via the free KEW Smart Advanced app. No clipboard, no re-keying, no transcription mistakes — just clean, time-stamped records ready to drop into a compliance report.

Key Benefits That Matter on the Job

Lightning-fast 0.5-second measurement → more tests per day → higher productivity. When you’re working through a multi-circuit board or a string of solar panels, half-second readings let you keep a rhythm instead of standing around watching a display settle.

Six test voltages (50V to 1000V) → one tester for nearly every job → less gear in the ute. From sensitive electronics and control wiring at 50–125V, through standard installation testing at 250–500V, to solar and HV applications at 1000V, a single instrument has the range covered.

Bluetooth 5.0 + onboard memory → paperless, error-free reporting → faster certification. Save results on the tester, sync wirelessly to the KEW Smart Advanced app on Android or iOS, and generate professional reports without manual data entry. KEW Report PC software is also available for desktop reporting.

Automatic discharge → safer handling → peace of mind. When an insulation test finishes, any electric charge stored in the tested object is discharged automatically, protecting you from a nasty surprise on capacitive loads like cables and motor windings.

Continuity testing at 200mA → AS/NZS 3000-compliant earth checks → complete verification. Built-in low-resistance continuity testing lets you verify protective earthing and bonding conductors as part of the same workflow.

Rugged build with backlit display → works where you do → reliable in the field. A backlit LCD makes readings easy in dim switch rooms and roof cavities, and the robust housing is rated to handle the knocks of daily trade use.

Technical Specifications

Model family note: The 3550 series comes in three variants. The KEW 3551 is the standard model, the KEW 3552 adds memory, and the KEW 3552BT (this model) adds both memory and Bluetooth communication — the right choice if wireless reporting matters to your workflow.

Applications & Use Cases

Electrical contractors & sparkies: Commission new installations and verify insulation resistance and earth continuity under the AS/NZS 3000 Wiring Rules. Run periodic testing on existing switchboards, submains and final subcircuits, then sync results for instant certificates.

Solar PV installers: Use the 500V and 1000V ranges to test PV array and string insulation resistance in line with AS/NZS 5033 and IEC 62446-1 commissioning requirements. The 40GΩ ceiling and fast readings make string-by-string testing efficient on big rooftop and ground-mount arrays — ideal for CEC-accredited installers documenting handover.

Industrial & facility maintenance teams: Schedule predictive maintenance on motors, cables, transformers and control gear. Trend insulation resistance over time using saved memory data to catch degrading insulation before it becomes a failure or a shutdown.

Technical educators & RTOs: A clear, fast, app-connected tester makes an excellent teaching instrument for TAFE and RTO electrical programs, letting students see live readings on a tablet via Bluetooth.

Anyone who has spent a day fault-finding around a switchboard knows the routine — swap leads for the insulation tester, swap again for the earth tester, then reach for the multimeter to confirm the circuit’s dead. Three instruments, a tangle of leads, and a real risk of triggering an RCD trip the moment a small test current sneaks down the earth path. On a busy commercial fit-off or a rooftop solar job, that lost time adds up fast, and a nuisance trip can mean climbing back into the roof space to reset a board.

For Australian trades working to AS/NZS 3000, insulation resistance and earthing checks aren’t optional — they’re the backbone of safe verification. The challenge has always been doing them quickly, accurately and without dragging a kit bag of separate testers up a ladder.

The Solution: Three Tests, One Pocket-Sized Probe

The KEW 6041BT collapses that whole workflow into one palm-sized tester you can hold like a pen. Press the tip to the conductor, hit TEST, and you’ve got insulation resistance, earth resistance or voltage at a glance. KYORITSU built it around a simple idea — get the technician released from test-lead hassles — and the result is an instrument that’s genuinely faster to use on real jobs.

It measures insulation resistance across four ranges (50, 125, 250 and 500 V), checks earth resistance using a simplified 2-pole method, and reads True RMS voltage up to 440 V AC/DC with automatic AC/DC detection. A built-in illuminance sensor wakes the LED light and backlight in dim plant rooms, and glow-in-the-dark switches help you find the controls when you’re working in a dark roof cavity. Crucially, the earth function uses a test current of 2 mA or less, so you can take earth readings on live installations without unintentionally tripping the RCD.

Key Features and What They Mean on the Job

• All-in-one probe design – Insulation, earth and voltage testing in a single 230 g body you operate one-handed. Less gear in the bag, fewer leads to swap, faster results between points.
• Anti-trip earth testing (≤2 mA) – The low test current on the earth function avoids unintentional RCD trips, so you keep measuring on live boards without resetting protection devices.
• Live circuit warning – On both insulation and earth functions, an audible alert plus a red LCD backlight flag dangerous voltage (30 V or higher) and lock out measurement until it’s safe. A built-in safeguard before you apply test voltage.
• True RMS voltage to 440 V – Accurate readings on distorted waveforms common around VSDs, inverters and switching loads, with AC/DC auto-detection so there’s one less setting to get wrong.
• Comparator function with audible pass/fail – Set a threshold and the tester beeps and lights up when a reading falls outside it, so you can run repetitive checks without squinting at every value.
• Auto-discharge – Stored charge on the circuit under test is automatically bled off after an insulation test, protecting you and the equipment.
• Bluetooth 5.0 to KEW Smart Advanced – Save readings straight to your phone or tablet, capture location data, and drop results into the supplied Excel report template — paperwork done before you’ve packed up.
• App-based customisation – Disable ranges or functions you don’t use, change the maximum displayed value, or adjust comparator thresholds to suit your workflow and reduce the chance of accidental high-voltage output.
• Replaceable metal tips – Standard, long and moulded tips are available, plus an optional L-shaped probe for awkward, high or recessed terminals.
