Inte - Model KQ500 -Fixed Gas Detector

with years of 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.  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. The detector has high sensitivity, quick response, long lifetime, polarization time and many other characteristics; it is among the first class in similar products in China.
