Testo 316-2 Gas Leak Detector 0632 3162 for Methane, Propane and Hydrogen Product Description The testo 316-2 gas leak detector. For pinpoint detection of gas leaks Even if you already know that a pipe is leaking, you normally still have a long way to go before you can actually locate the leak. The testo 316-2 gas leak detector is just the right tool for carrying out such pinpointing detection. The detector’s easy-to-read 18-step bar display and maximum leakage reading show the concentration of combustible gas in the surrounding air and lead you quickly and reliably to the source of the leak. The detector also has an audible alarm that warns you when a threshold is crossed and a headphone jack which allows you to connect earphones for more focused and productive working in loud or distracting environments.
