Product description

GJG100J (A) high-concentration laser methane sensor for coal mines adopts the laser absorption spectroscopy technology. It is a high-performance methane monitoring instrument with accurate measurement, long calibration cycle, and no interference from water vapor and other cross gases, mainly used in coal mines and other places where methane concentration needs to be monitored.

Features

◎The laser gas detection module is packaged independently and can be disassembled and replaced as a whole, convenient for maintenance;

◎Temperature self-adaptation and compensation. The measured value is independent of changes in ambient temperature;

◎Pressure compensation. The measured value is independent of pressure changes;

◎Local 5-digit red digital display, with a sound and light alarm;

◎Support frequency, RS485 and CAN signal transmission.
