Detailed description

GJG100J mine high concentration laser methane sensor

GJG100J mine high-concentration laser methane sensor is a full-range, high-precision methane sensor, which transmits and measures through optical signals. The sensor displays the methane concentration value in real time and continuously and automatically converts the methane concentration value into a standard electrical signal for transmission to the mating device. The output power is only 0.2mW, which is suitable for flammable, explosive, strong electromagnetic interference and remote unmanned monitoring environments such as underground coal mines, gas power generation, and garbage disposal sites.
