0-4.00% cH4 Gas Detector JCB4 methane gas oxygen gas detector for Coal Mine

Product Description
JCB4 portable methane detection alarm instrument is suitable for continuous detection of methane (gas) concentration in the environment of coal mines, roadways and other places. When methane or carbon monoxide concentration exceeds the limit, it can automatically issue sound, light, vibration alarm and light bar alarm. This detector can be used by relevant staff, managers, professionals, mobile workers, coal mine defense personnel, etc., and can also be used fixedly in the above places. The explosion-proof type of the instrument is intrinsically safe and explosion-proof type for mining, and the explosion-proof mark is Eⅹibdl.
