Features & Benefits

The Whisper Ultrasonic Leak Detector is ideal for detecting and locating sources of ultrasonic sound through the use of sophisticated electronic circuitry.

Unaffected by audible noise, Whisper incorporates an Internal Noise Control allowing for use in extremely noisy environments, such as mechanical plant rooms, and around operating chillers.

Because Whisper is designed to detect ultrasound at 40.5 kHz, not even a murmur will escape detection.

Use the optional transmitter for quick and accurate leak checking in walk-in coolers / freezers, wall and ceiling joints, around doors, windows, ducts, etc.
