The Whisper hand held 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 a gas moving through a leak site, making it a super versatile tool for leak checking ANY gas in pressurised or vacuum systems.

If there is any leak that a gas detector, soap bubbles or a dye injection system can’t address, the Whisper is what you need. 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 pinpoint 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.

For the ultimate in performance and versatility, consider the Whisper with accessory kit. Along with the leak detector, this kit gives you more accessories for more productivity. Use the contact probe to check machinery’s function. Simply twist the metal probe onto the instrument and touch it to bearing housings, solenoids, pistons and other mechanical equipment to allow frequencies to travel into Whisper’s ultrasonic transducer. Properly functioning machinery sounds smooth and clear, a sharp contrast to 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.

Whisper Transmitter, contact probe, and premium headphones are included in the accessory kit, or can be purchased separately for use with the standard package.
