INFICON Whisper Ultrasonic Leak Detector
The INFICON Whisper detects ultrasonic sound produced by leaks and certain mechanical faults. It helps maintenance teams investigate suspected leak locations in compressed air, pneumatic and vacuum systems.

How Ultrasonic Leak Detection Works
Gas moving through a small opening under a pressure difference can generate ultrasound. Whisper converts detected ultrasound into audible sound through headphones, helping the operator trace its source.
This method detects sound rather than identifying the gas. Results depend on the leak conditions, access and competing ultrasonic sources.
Typical Inspection Tasks
- Compressed air: investigate suspected leaks around connections and fittings.
- Vacuum systems: trace air entering through leaking points.
- Machinery: use the optional contact probe for checks on bearings and other components.
- Enclosure seals: use the optional Whisper Transmitter to investigate sound escaping through gaps.

Selecting Your Instrument and Accessories
Confirm the package contents when requesting a quotation. The contact probe and Whisper Transmitter are accessory options; they should not be assumed to be included with every instrument.
For selection assistance, tell us:
- Which system you need to inspect
- Whether it operates under pressure or vacuum
- Where the suspected leaks are located
- Whether you also need machinery or enclosure checks
