INFICON Whisper Ultrasonic Leak Detector

Whisper Is Ideal For Locating Ultrasonic Frequencies

The Whisper Ultrasonic Leak Detector allows the user to check for pressure and vacuum leaks where other sniffer style leak detectors can’t go. With the unique internal noise control circuitry, you can operate Whisper in high noise environments.

The Whisper handheld leak detector offers versatility and flexibility for a variety of applications, not just refrigeration or air conditioning. Whisper uses ultrasonic technology to listen for the sound of gas moving through a leak site, making it a super versatile tool for leak checking ANY gas in pressurised or vacuum systems.

Use Whisper Transmitter to test seals around any enclosed space, including doors, windows, ducts and refrigerator cases. Simply turn Whisper Transmitter on to generate its ultrasonic tone and place it in the area you wish to leak test. Trace around potential problem areas with Whisper to alert you to the transmitter’s ultrasonic frequencies “leaking” through poorly-sealed areas.
