Ultrasonic Leak Detection
The Inficon 711-202-G1 Whisper is a digital ultrasonic leak detector designed for locating pressurised gas escapes in refrigeration, HVAC and compressed-air systems. It converts high-frequency sound from leaks into audible signals so technicians can pinpoint faults quickly. The kit includes a carrying case, headphones and an extension probe for immediate field use.
Intended users and limits
Suited for service engineers and maintenance crews who need a portable, battery-operated tool to find refrigerant or air leaks without dye or soap. Not suited for buyers who require a refrigerant-specific sniffer that identifies gas type or concentration, or for anyone needing a fixed-mount continuous monitoring system.
Core detection method
Ultrasonic sensing detects the turbulence noise created by any pressurised leak regardless of gas type, making the technology versatile across different refrigerants and compressed gases. The included extension probe allows access to confined fittings and the supplied headphones isolate the signal in noisy environments.

Questions about this item
What comes in the box to help the Whisper 711-202-G1 reach tight leak points?
The kit includes an extension probe that threads onto the sensor head, letting you probe around fittings and ductwork without removing panels.
How do you set up the Whisper 711-202-G1 for the first time, and what step do users often skip?
Insert the batteries, plug the supplied headphones into the jack, then press the power button and adjust the sensitivity dial until background noise just disappears — skipping the dial adjustment leaves the unit either deaf or screaming.
Which wearable part on the Whisper 711-202-G1 will need replacement after heavy shop use?
The foam ear cushions on the included headphones compress over time; replacements keep the ultrasonic signal isolated from shop noise.
