Price Match Guarantee & Advice

Ideal for testing for refrigerant leaks in noisy environments, the Testo 316-4 is able to detect CFC, HCFC, HFC and H2 refrigerants and give both audible and visual indication that a leak has been detected.

Includes in the kit with this leak detector are a set of earphones which can be used in combination with the device to hear the audible tone in noisy industrial environments. With the use of the device’s integrated screen which shows contaminants and malfunctions, carrying out leak detection is simple and easy.

The 316-4 also has high sensitivity built in, allowing it to detect even tiny leakages. If a leak is detected, the device’s screen will flash with a red colouring, and the audible tone will sound. There’s also a trend display which shows maximum leakage.
