• Detectable gases Methane (CH4), Propane (C3H8), Hydrogen (H2), Butane (C4H10)
• Acoustic and visual alarm via multi-color LED on the sensor head
• Display of ppm / vol% / %LEL on the instrument
• Sensor self-test and automatic zeroing
• Flexible probe for locations that are difficult to access

If you like to keep things simple, we recommend the testo 316-1 gas leak detector: Identifying and locating leaks or even reading off concentration values in ppm or %LEL (lower explosive limits) are all exceptionally easy. No training required thanks to the intuitive traffic-light scale on the head and the display illumination.
