GS40 | Electronic Combustible Gas Detector

Handheld Electronic Combustible Gas Detector

The GS40 is a completely self contained combustible gas leak detector designed to pinpoint gas leaks in the most 
demanding applications. An efficient and sensitive gas sensor is combined with solid state circuitry which provides 
an audible alarm that increases in pitch as the concentration of the gas increases. A visual indication is also 
provided as well as provisions for an earphone for use in noisy environments.
