Inficon Whisper Ultrasonic Leak Detector

Supplied By Alpha

The Whisper is ideal for detecting and locating ultrasonic frequencies generated when leaks of any gas under pressure or vacuum occur.

The leak detector includes a specialized built-in receiver that detects frequencies in the 40.5 kHz range.

The Whisper locates the ultrasound’s source, while an internal noise control ensures the instrument is unaffected by audible noise.

This makes the Whisper ideal for noisy environments, such as mechanical rooms.

The 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 idenitified 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.
