Inficon 711-202-G1 - Whisper® Ultrasonic Leak Detector

Versatility And Flexibility For A Variety Of Applications

If you have a non-traditional leak detection application that a gas detector, soap bubbles or dye injection system can't address, Whisper is ideal for detecting and locating ultrasonic frequencies generated when the following common situations occur:
  • Leaks of any gas under pressure or vacuum
  • Electrical arcing
  • Worn bearings and machinery
  • Malfunctions in steam traps
  • Leaking seals
The leak detector includes a specialized built-in receiver that detects frequencies in the 40.5 kHz range. Through sophisticated circuitry, Whisper locates the ultrasound's source, while an internal noise control ensures the instrument is unaffected by audible noise. This makes Whisper a versatile tool which can even be used in noisy environments, such as mechanical rooms.

Whisper incorporates heterodyne capability, which reduces the ultrasonic frequencies detected to a range that can be heard by the human ear. Variations can therefore be identified to easily pin-point the ultrasonic source. Heterodyne output is enabled when headphones (included) are plugged in to the detector. Sensitivity is adjusted through an innovative touch pad. Multiple LEDs and an audible alarm register the leak when heterodyne mode is not enabled.
