Superior Signal – VPE-2000 Digital Ultrasonic Leak Detector

The VPE-2000 Ultrasonic Leak Detector is a professional diagnostic instrument designed to locate air, gas, vacuum, and refrigerant leaks quickly and accurately. With digitally controlled heterodyne technology, 256-step sensitivity adjustment, and dual probe detection, it converts ultrasonic signals into audible sound for efficient troubleshooting in industrial environments.

  • Advanced Ultrasonic Detection: Detects compressed gas, vacuum, and refrigerant leaks
  • 256-Step Digital Sensitivity & Volume Control for precise signal tuning
  • Visual + Audio Monitoring: LED bar graph with digital display and peak hold
  • Long Battery Runtime: 55–80 hours operation with 9V battery

Description

The VPE-2000 Ultrasonic Leak Detector is designed for industrial maintenance professionals, plant engineers, and facility technicians who need reliable diagnostic tools. Featuring digitally controlled heterodyne conversion, the device captures ultrasonic signals within 16–42 kHz frequency ranges and converts them into audible sound for quick analysis. The dual detection modes, including airborne and touch probe sensing, allow technicians to inspect leaks, valves, bearings, and mechanical components with high accuracy.

Equipped with 256-step digital sensitivity and volume control, the VPE-2000 enables users to fine-tune detection settings even in noisy environments. The 20-element LED bar graph with digital alphanumeric display provides simultaneous visual and numerical readings for easy comparison. Built with a durable aluminum and ABS housing and featuring digital peak hold and memory storage, this device is ideal for industrial plants, hospitals, schools, hotels, and manufacturing facilities performing preventive maintenance and leak detection.
