Product description
Main characteristics
● uses the spectral absorption principle to measure the methane gas concentration, accurate measurement, stable work, without user calibration, and can work online for a long time.
●The sensor outputs standard frequency or RS485 digital signal that can be used online with other controllers such as the monitoring station.
● is suitable for environments where gas and coal dust explosion are dangerous underground in a coal mine.
