DatasheetSafely tracking down gas leaks with the testo 316-2 gas leak detector
Even if you already know that a leak exists but still need to locate it, the gas leak detector provides exactly the right tool: the 18-stage bar graph display as well as the maximum leak indication show the gas concentration on the display and reliably guide you to the source of the gas leak. An acoustic alarm also warns when limit values are exceeded. Particularly practical is the fact that the testo 316-2 gas leak detector features a headphone output: thanks to the supplied in-ear headphones, you can clearly hear the acoustic alarm even in noisy environments.

Applications
Gas leak detection on gas pipelines in heating environments
Gas leak detection is an essential inspection of gas pipeline components for tightness or the presence of a leak. A gas pipeline is considered tight if no gas escapes from the pipeline at exposed points. This means that especially openly installed gas pipelines are checked for external tightness. Leaks are detected by probing connection points, e.g. at fittings, flanges, threaded connections, and gas control valves. Checking building entry points and concealed gas pipelines in cavities at air outlet points is also important. State-of-the-art gas leak detection involves the use of an electronic gas leak detector (“sniffer”).
