Portable Gas Detector/ Portable CH4,O2,CO,H2S multi-gas detector
Applications:
CD4 portable Multi-gas detector is an intrinsically safe and explosion-proof instrument and is designed to deter the gases. It can simultaneously monitors up to four atmospheric hazards including carbon monoxide (CO), oxygen (O2), combustible gas (%LEL), and hydrogen sulphide(H2S). Compact and lightweight, CD4 portable Multi-gas detector activates audible, visual and vibrating alarms in the event of a low or high alarm condition.
CD4 portable Multi-gas detector is unparalleled in its versatility, capability and overall value. Water-resistant line of portable gas detectors has transformed the market with its matchless array of features.
It is used at the underground coal mine and mine safety inspection mainly. Certainly, it is also applied to fire fighting, confined space, chemical industry, oil and all kinds of environment that needed to measure the hazardous and toxic gases
