GAS HUNTER™
Portable Combustible Gas, Oxygen, and Carbon Monoxide Detector & Pressure Gauge
The Gas Hunter™ is a versatile instrument capable of measuring levels of combustible gas, O2, CO, and pressure.
In the field, the Gas Hunter™ does the job of seven individual instruments to optimize technician efficiency in leak survey operations and customer service calls. It is able to sniff out combustible gases from part per million levels to 100% by volume through auto-ranging. But there’s more. The Gas Hunter™ is also able to measure the levels of %O2 and ppm CO, and measure pressure in the range of 0.0 to 27.7 in H2O.
