Reference leak comparison of Fieldpiece SRL8 Testo 316-3 and Bacharach Informant 2

This is just a quick test comparison of the three different leak detectors on HFC and CFC refrigerant reference leaks. The PPM testing is on another video. To sum up: The SRL8 picks up the HFC about 2 inches away and is much more sensitive. The Testo 316-3 picks up HFC about 1/8 inch away and the Bacharach Informant 2 doesn't seem to pick up the HFC at all.
