GJG100HInfrared methane sensor, gas detector

It is a fixed intrinsic safety detection instrument specifically used to monitor the concentration of gas in gas pipelines. This instrument adopts "Non Dispersive Infrared" (NDIR) gas detection technology, digital temperature and pressure compensation, integrated dust water separation technology, etc., effectively overcoming the influence of various parameter changes such as target gas temperature, pressure, humidity, background gas in the pipeline, achieving accurate and continuous measurement of gas in the range of 0% CH4-100% CH4 and displaying it on site. At the same time, the gas concentration value is converted into standard electrical signals and transmitted to related equipment. The instrument is suitable for gas detection in applications such as coal mine gas drainage pipelines, gas drainage pump stations, gas station transmission pipelines, gas power plant transmission pipelines, urban gas pipelines, natural gas transmission pipelines, etc.
