Good 2 Wires 4-20mA Fixed Gas Detector

Fixed Gas Detector brief introduction: 
This series of gas detection transmitter use imported electrochemical sensors (combustible gas using catalytic type), this new gas detection transmitters have been developed with years of experience in the development and production of gas detections, and can be widely used in metallurgy, petroleum, chemical, coking, municipal, gas, sewage treatment and special industries, and apply for continuous monitoring of a variety of gas concentration in working environments. Transmitters use explosion-proof design, 4mA ~ 20mA standard signal or directly into the DCS system, this transmitter is high sensitivity, fast response, long life, short polarization time and so on. Our products have achieved the domestic similar product advanced level.
