The leak detector includes a specialized built-in receiver that detects frequencies in the 40.5 kHz range. Through sophisticated circuitry, Whisper locates the ultrasounds source, while an internal noise control ensures the instrument is unaffected by audible noise. This makes Whisper a versatile tool that can even be used in noisy environments, such as mechanical rooms.

Reducing Ultrasonic Frequencies

Whisper incorporates heterodyne capability, reducing the ultrasonic frequencies detected to a range the human ear can hear. Variations can, therefore, be identified to pinpoint the ultrasonic source easily. The heterodyne output is enabled when headphones (included) are plugged into the detector. Sensitivity is adjusted through an innovative touchpad. Multiple LEDs and an audible alarm register the leak when the heterodyne mode is not enabled.

Consider the Whisper with accessory kit for ultimate performance and versatility. Along with the leak detector, this kit gives you more accessories for productivity. Use the contact probe to check the machinery s function. Twist the metal probe into the instrument and touch it to bearing housings, solenoids, pistons, and other mechanical equipment to allow frequencies to travel into Whispers ultrasonic transducer. Properly functioning machinery sounds smooth and clear, contrasting with malfunctioning machinery.

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.
