Fixed Gas Detection 4-20mA Analog Online NH3 Ammonia Gas Detector
Sensor
Introduction:
This series of gas detection transmitter uses imported
electrochemical sensors (combustible gas using catalytic type).
This gas transmitter has 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.
