Accutrak VPX-WR Ultrasonic Leak Detector (w/ Dynamic Noise Discrimination)

Accutrak VPX-WR Ultrasonic Leak Detector (w/ Dynamic Noise Discrimination)

Accutrak VPX-WR Ultrasonic Leak Detector (w/ Dynamic Noise Discrimination)

Description

• The VPX-WR is an ultrasonic leak detector equipped with Dynamic Noise Discrimination (DND) technology, making it one of the most powerful gas leak detectors available.

• An excellent choice for schools, hospitals, hotels, factories, and other large institutional or industrial settings.

• Highly regarded for compressed gas leak detection and suitable for various plant maintenance tasks.

• Features an ultra-durable, waterproof design built to withstand tough environments and adverse conditions.

• Easy to use with simplified single‑control operation.

• Wide frequency range from 20 kHz to 100 kHz with no need for manual tuning.

• Provides output to an analyzer in either converted or raw signal formats.

• Housed in a cylindrical, hard‑black anodized aluminum body with rubber foam grip and fully sealed LEMO connectors.

Applications

• Leak detection – Effective for air, vacuum, refrigerants, and any gas.

• Steam traps – Quickly identifies live steam loss within seconds.

• Valves – Detects internal leaks in check, ball, needle, gate, or any valve; diagnoses thermal expansion valves in just five minutes.

• Bearings – Identifies wear and lubrication issues before damage occurs.

• Electric arc and corona – Inspects circuit breakers, relays, bus bars; checks for contact corrosion and insulation integrity.

• Pneumatics and hydraulics – Facilitates inspection of controls, hoses, tools, fittings, and internal cylinders.

• Vibration – Detects ultrasonic sounds generated by excessive friction.

• Fan belts – Monitors fan belt performance issues.
