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.
