The IG8140 type four in one fixed online gas detector is a multi-function, intelligent and fully automatic detection instrument that is installed at a specific detection point 24h, which continuously detects gas concentration. The instrument has the function of accurate detection of gas concentration, at the same time, it has the detection of ambient temperature and humidity, and the pipeline installation and detection of pressure reducing and limiting flow function. The instrument outputs 4-20mA standard current signal, and has RS485 (Modbus RTU) signal output. It is compatible with all kinds of control alarm, PLC, DCS and other control systems, which can realize remote monitoring, remote alarm, data storage and other functions. The infrared remote control operation can complete the debugging and calibration remotely.
