Stop Fighting Unstable Pressure During Critical Calibrations

You’re on-site calibrating pressure transmitters, and your traditional hand pump is making you work twice as hard. You’re pumping frantically to reach 30 bar, the pressure keeps drifting, and you’re burning valuable time trying to maintain stability long enough to record a reading. Meanwhile, your client’s production team is waiting for you to finish, and you’re questioning whether your calibration certificate will hold up under scrutiny.

The Additel ADT992 Handheld Pneumatic Pressure Pump eliminates this frustration. Designed specifically for field calibration professionals, this pump delivers consistent pressure generation from 95% vacuum to 700 psi (50 bar) – covering the vast majority of industrial pneumatic calibration requirements across Australian HVAC, compressed air, and process instrumentation applications.

Dual-Stage Engineering: Work Smarter, Not Harder

The ADT992’s dual-stage piston design fundamentally changes how you approach pressure calibration. The pre-pressure piston rapidly builds bulk pressure with minimal physical effort – you’ll reach 40 bar faster than with conventional hand pumps, without the arm fatigue. Once you’re approaching your target pressure, the fine adjustment screw (7.2 ml volume capacity) provides precise control for hitting exact calibration points.

Each lever stroke delivers a +30 psi (2 bar) boost, giving you predictable, controlled pressure increases. The 10 Pa (0.1 mbar) adjustment resolution means you can dial in precise pressure values required for tight-tolerance calibrations. This isn’t just convenient – it’s the difference between completing 10 calibrations per day versus 6, and arriving home without exhausted forearms.

Built-In Vacuum Capability: One Pump, Complete Pressure Range

Unlike basic pressure-only hand pumps, the ADT992 generates vacuum down to 95% (approximately -950 mbar), making it genuinely versatile for calibration technicians who work with both positive pressure and vacuum instruments. Calibrating vacuum switches, negative pressure transmitters, or differential pressure devices no longer requires carrying separate equipment.

The minimum pre-pressure of 600 psi (40 bar) means you can efficiently generate high pressures without excessive pumping cycles, while the 35 ml maximum load volume provides the capacity needed for testing larger-volume pressure systems without constant re-pumping.

Multi-Position Versatility: Designed for Real Job Sites, Not Just Lab Benches

Australian trade professionals work in cramped plant rooms, alongside running machinery, on elevated platforms, and in confined spaces where traditional hand pumps become awkward or impossible to operate effectively. Additel engineered the ADT992 with this reality in mind.

The adjustable reference port and dual rubber grips enable horizontal, vertical, or tilted operation – whatever orientation suits your specific installation. Calibrating a wall-mounted pressure transmitter at head height? Work vertically. Testing equipment on a workbench? Operate horizontally. Awkward installation in a tight mechanical room? Adjust the pump to whatever position gives you access.

At just 1.6 kg (3.5 lbs) and measuring 320mm x 110mm x 122mm (base x width x height), the ADT992 fits in your toolkit alongside multimeters and clamp meters, not in a separate bulky case that stays in the van.

Integrated Filtration Protects Your Calibration Standards

The ADT992 includes built-in port filters that protect both your pump and your precision calibration instruments:

• Standard port: 150μm quick-removal filter prevents contamination entering your reference gauge or calibrator
• Pump air intake port: 100μm quick-removal filter protects internal components from dust and debris
• Pressure outlet: 150μm quick-release filter ensures clean pressure delivery to your device under test

These filters are critical when working in dusty industrial environments, mining facilities, or outdoor installations where airborne contamination would otherwise compromise measurement accuracy or damage sensitive instruments. The quick-removal design means you can clean or replace filters on-site without tools.

Hand-Tight Quick Connectors: Faster Workflows, No Tools Required

Every model includes the ADT100-X-FNG female quick connector for your device under test (DUT), with configurations available in 1/4NPT, 1/2NPT, 1/4BSP, 1/2BSP, or M20X1.5 to match your specific equipment. The hand-tight design means you can swap between different instruments without reaching for spanners – critical when you’re rotating through multiple calibration points or testing several devices in succession.

When you’re working through a calibration schedule with 15 pressure transmitters to verify, these seconds per connection add up to significant time savings across your day.

Materials and Construction: Built for Australian Industrial Environments

The ADT992 uses stainless steel ram/adapters and a combination SS/aluminium body construction with Buna-N, PTFE, and Copper Alloy seals – materials selected for durability, chemical resistance, and reliable performance across diverse Australian conditions.

Whether you’re working in tropical Queensland humidity, dry inland mining facilities, coastal industrial plants with salt air, or temperature-controlled metropolitan facilities, the custom-machined components maintain leak-free operation. The robust construction withstands the inevitable knocks from being transported between sites, dropped in toolboxes, or used on vibrating equipment platforms.
