Portable Gas Detector/ Methane CH4 & Carbon Dioxide CO gas Detector
Applications:
CJT-4/1000B portable CH4 &CO in 1 gas detector is an intrinsically safe and explosion-proof instrument and is designed to deter the gases. It can simultaneously monitors carbon monoxide(CO), combustible gas (%LEL). Compact and lightweight, CJT-4/1000B portable CH4 &CO in 1 gas detector activates audible and visual alarms in the event of a low or high alarm condition.
CJT-4/1000B portable CH4 &CO in 1 gas detector is unparalleled in its versatility, capability and overall value.
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
