Product Overview:
KQ500 series fixed gas detector(also gas transmitter): with 6 years experience in designing and producing detector, we develop our new product with electrochemical sensor. It can be widely used in metallurgy, petrol, petrifaction, chemistry, light industry, coking, municipal administration, gas, pharmacy, sewage dealing and many other special industries and fields.
It can detect various gases such as flammable gas, O2,H2S,CO,HCN,NO2,SO2,NH3,HCL,CL2,H2 etc. The device adopts intrinsic safety type channel design, standard 4~20mA two wires signal output. It can transfer data in long distance, can get into the DSC system directly. it is among the first class in similar products in China.
Main features:
l It can detect more kinds of gas. high precision
l Fixed explosion-proof shell; it’s safe and reliable
l Standard 4-20mA electric current output, compatible with existing alarm control unit or DSC (distributed control system).
l best sensor, high sensitivity, rapid response, stable and reliable
l operation is simple; easy installation and maintenance
