testo 316-EX – Gas leak detector

Code: G7c-1-1-1-1

The testo 316-EX gas leak detector helps you detect gas leaks. Gas verification and gas leak location can be carried out on gas pipes and installations both indoors and outdoors.


Product Description

  • ATEX approval (94/9/EC)
  • ppm and vol.% display
  • Flexible probe for inaccessible areas
  • 3 different types of gas can be detected: methane, propane and hydrogen
When house owners notify the network operator or fitter that they can clearly smell gas in the house, a highly explosive gas concentration may already be present (4–17%). The fitter has to use a gas detector to check sections of gas pipes for leak tightness to locate possible leaks.
The testo 316-EX gas leak detector offers EU ATEX protection (ATEX approval 94/9/EC). Use the multi-range gas detector to detect methane, propane and hydrogen gases. The gas concentrations are measured in the ppm range with a semiconductor sensor and are shown on the display with a resolution of 1 ppm. Flexible measuring probes mean you can search for leaks even in inaccessible areas.
