The Testo 316-3 leak detector is one piece of kit that you as a refrigerant technician just won’t want to be without. The handheld leak detector can detect all the most common cooling agents and the smallest leaks.

The instrument is ready for use immediately after switching on, without the need for selecting a characteristic curve. Thanks to the automatic zeroing, the testo 316-3 detects leaks even in rooms which have already been contaminated.


High sensitivity < 4 g/a allows the detection of the smallest leaks.
Detects all common refrigerants.
Easiest possible operation thanks to a single button.
Immediate readiness with no pre-settings.
LED indicator of leakage with simultaneous audible alarm.


The electrochemical sensor has a service life of approximately 100 operating hours. Once this time is up, or if you suspect that some leaks have not been detected, the sensor must be replaced.
