Safely detect combustible gas and flammablerefrigerant leaks.
GAS-Mate is an intrinsically safe combustible gas leak detector that can safely and reliably detect leaks of combustible gases, flammable refrigerants, and hydrogen forming gas. It is a versatile tool for use in heating, air conditioning, refrigeration, andautomotive applications. You can leak check with confidence knowing GAS-Mate is backed by an industry-best three-year warranty. 
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 sulfide. 
Features
Multiple LEDs, variable intensity audio alarm indicate leak strength
Adjustable sensitivity helps pinpoint leaks fast
Made in the USA
Advantages
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 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
