Part #: 0632 3172


Gas pipe connections can be safely and efficiently tested with the testo 317-2 gas leak detector. The handy gas detector for new users detects two types of gas: methane and propane. The gas concentration is shown via a bar display. In addition, the gas leak detector indicates increasing gas concentrations via an acoustic alarm. The measuring instrument also confirms acoustically that it is ready for measuring.

  • Shows gas concentration in visual bar display
  • Sensor self-test following switch-on
  • Audible confirmation of readiness to operate
  • Increasing alarm sounds with increasing gas concentration
  • Continuous sound if alarm threshold is exceeded
  • Battery monitoring with optical display
  • Self-test function
