Accutrak VPE-1000 Digital Ultrasonic Leak Detector

Accutrak VPE-1000 Digital Ultrasonic Leak Detector

Accutrak VPE-1000 Digital Ultrasonic Leak Detector

Description

• The VPE‑1000 is a digital ultrasonic leak detector designed for schools, hospitals, hotels, and other large institutional or industrial settings.

• Offers versatility for numerous leak detection and plant maintenance applications.

• Uses digitally controlled heterodyne technology to convert ultrasound (34 kHz–42 kHz airborne, 16 kHz–24 kHz via touch probe) into an audible range.

• Features a 20‑element bar graph with peak‑hold and a separate alphanumeric digital display for simultaneous readings and comparisons.

• Provides 256‑step digital sensitivity control and 256‑step digital volume control with Audio Zoom.

• Built with a rugged aluminum and ABS body (anodized gold finish on aluminum, black ABS).

• Runs on a standard 9 V battery with 55–80 hours of run time.

Applications

• Leak detection – Air, vacuum, refrigerants, and any other gases.

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

• Valves – Identify internal leaks in check, ball, needle, gate, or any valve; diagnose thermal expansion valve issues in just five minutes.

• Bearings – Detect wear and lubrication problems before significant damage occurs.

• Electric arc and corona – Inspect circuit breakers, relays, bus bars; check contact corrosion and insulation integrity.

• Pneumatics and hydraulics – Inspect controls, hoses, tools, fittings, and internal cylinders.

• Vibration – Detect ultrasonic sounds generated by excessive friction.

• Fan belts – Monitor and diagnose potential issues.
