Safely detect flammable refrigerant and combustible gas leaks!


The INFICON raises the bar on combustible gas detectors with GAS-Mate, the ideal tool for locating leaks in forming gas, flammable refrigerant, or combustible heating and appliance applications.  GAS-Mate is also intrinsically safe, so you can leak check with confidence.

GAS-Mate outperforms other models with twice the sensitivity of many competitors – down to 5 ppm methane, the main component of natural gas. GAS-Mate also detects many other combustible gases, such as ammonia, propane, ethanol and hydrogen sulphide.

No calibration is required for GAS-Mate or its field-replaceable sensor. Simply turn the unit on, allow it to warm up for a few seconds and it is ready to quickly pinpoint any gas leaks present.

To prove that GAS-Mate has the performance and durability for your job, it carries an industry-leading, 3-year over-the-counter replacement warranty – three times what most other manufacturers offer.

Safely detect flammable refrigerant and combustible gas leaks! … GAS-Mate outperforms other models with twice the sensitivity of many competitors GAS-Mate outperforms other models with twice the sensitivity of many competitors – down to 5 ppm methane



  • Sensitive to 5 ppm methane
  • Also detects natural gas, forming gas, propane, butane, cyclopentane, ethane, ethanol, isobutane and ammonia
  • Great for flammable refrigerants like R290, R600a, and R441a!
  • Detects forming gas (95% nitrogen, 5% hydrogen)
  • Auto zeroing for ignoring background gas levels in a leak test area
  • Small sensor and probe tip permit leak checking in tighter places
  • Certified intrinsically safe by MET Laboratories for use in combustive/explosive environments
  • Multiple LEDs, variable intensity audio alarm indicate leak strength
  • Adjustable sensitivity helps pinpoint leaks fast.
