Superior Signal Superior AccuTrak – VPX-WR / VPE-2000 Combo Kit

The VPX-WR and VPE-2000 Ultrasonic Leak Detectors are high-performance diagnostic tools designed for industrial and institutional environments. With dual ultrasonic detection modes, advanced sensitivity controls, and robust construction, these devices enable rapid and accurate detection of air, vacuum, and refrigerant leaks. Perfect for valve diagnostics, steam traps, bearings, electrical systems, and mechanical maintenance.

  • Wide Detection Range: Air, vacuum, and refrigerant leaks; any compressed gas
  • Dual Ultrasonic Modes: AFT & Heterodyne (VPX-WR), Digitally Controlled Heterodyne (VPE-2000)
  • Visual + Audio Monitoring: LED indicators, bar graph display, peak-hold function
  • Long Runtime & Robust Design: Ni-MH or 9V battery with up to 80 hours, aluminum and ABS construction

Description

The VPX-WR Ultrasonic Leak Detector is engineered for industrial maintenance, institutional facilities, and large-scale mechanical inspections. Featuring AFT and Heterodyne ultrasonic conversion, it can detect leaks in air, vacuum, and refrigerant systems, even under challenging noise conditions. With infinitely variable sensitivity and robust sealed connectors, it ensures reliable operation while detecting leaks from valves, bearings, and steam traps quickly and efficiently. Its rugged cylindrical aluminum body with foam grip makes it comfortable for extended use in demanding environments.

The VPE-2000 Ultrasonic Leak Detector combines digitally controlled heterodyne technology with a 256-step sensitivity adjustment and audio-visual monitoring for precise, repeatable inspections. Lightweight and ergonomically designed, its LED bar graph with peak-hold and alphanumeric display allows simultaneous reading of multiple measurements. Both devices are ideal for steam trap inspections, valve diagnostics, bearings, vibration analysis, electrical arc detection, pneumatics and hydraulics, and fan belt monitoring, providing technicians with reliable, real-time feedback for preventive maintenance and troubleshooting.

Application

VPX-WR Ultrasonic Leak Detector

  • Leak Detection: Air, Vacuum, Refrigerants; ANY GAS. Featuring DND technology, the VPX-WR is the most powerful gas leak detector on the market.
  • Steam Traps: Detect live steam loss in seconds.
  • Valves: Detect and hear internal leakage in check, ball, needle, gate, or any valve type. Diagnose thermal expansion valves in just five minutes.
  • Bearings: Hear wear and lubrication problems before damage occurs.
  • Electric Arc and Corona: Inspect circuit breakers, relays, and buss bars. Check for corrosion on contacts and proper insulation.
  • Pneumatics and Hydraulics: Inspect controls, hoses, tools, fittings, and internal cylinders with ease.
  • Vibration: Detect the ultrasonic sound generated by excessive friction.
  • Fan Belts: Monitor belt condition.
