The testo 316-2 is extremely user-friendly and ideally suited to fast check measurements thanks to its integrated pump, its optical presentation of the gas concentrations detected, and the integrated rechargeable battery.

Whether it’s for carrying out checks on flanges, fittings or any other places that are typically prone to leaking, the Testo 316-2 gas leak detector provides you with a speedy and sure means of detecting higher concentrations of methane, propane and hydrogen in the surrounding air.

Speedy and sure gas leak detection. The Testo 316-2 provides you with a quick and reliable means of detecting methane, propane and hydrogen in the ambient air. The gas concentration is displayed in the form of an easy-to-read bar and an alarm is triggered when a threshold is crossed.


  • Measures: Methane, Propane & Hydrogen
  • Quick reaction time with integrated pump
  • Flexible gooseneck sensor for checking hard-to-reach pipes and places.
  • 18-step bar for displaying gas concentration & maximum leakage display
  • Optical and audible alarm with bar display for increasing and dangerous gas concentrations
  • Trend display shows maximum leakage
  • Earphone connection for secure leakage localization in loud surroundings
  • High duration of use thanks to the rechargeable battery

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 that allows you to connect earphones for more focused and productive working in loud or distracting environments.
