Testo 316-3 Refrigerant Leak Detector Details

This device can be used to accurately determine leaks of CFC, HCFC and HFC refrigerants and includes high sensitivity of 4g/a to make sure that leaks are detected as quickly as is possible.

The sensitivity of the device is also completely adjustable, allowing users to compensate for things such as refrigerant build-ups or pooling.  This makes sure that even the smallest leaks can be detected, allowing the user to take action against leaks that may have went unnoticed when using less accurate testing instruments.

Good quality leak tester

Review by Malcolm (Posted on 18/02/2019)


I bought this for annual leak checking of aircon units installed where I work. I wondered how I was going to check that it works but actually found a leaky flare joint on a newly installed system straight away! Only a very small leak shown by soapy bubble test but the detector went berserk, even on the low sensitivity setting. It seems a well-made instrument and simple to use. It has both audible and visible indication of leaks so works well in a noisy environment.
