Testo 316-4 (Set 1) Refrigerant Leak Detector

£418.80 (inc. VAT)

The testo 316-4 (Set 1) is a fast and reliable leakage detector for all common refrigerants. The sensor is permanently monitored and shows malfunctions or contamination in the display. The use of test leaks is thus superfluous.

If dirty, the sensor can simply be cleaned, and is immediately ready for use again. The very high level of sensitivity of ⟨3g/a according to EN 14624 allows the detection of the smallest leakages. The display changes from green to red when leaks occur. An audible signal additionally indicates detected leakages. With the earphone, testo 316 can also be used in loud surroundings. The trend display shows maximum leakages and facilitates the localization of leaks. The flexible goose neck allows the optimum positioning of the sensor close to the pipe or other measurement site.
