Gas Detector and sensor

gas detectors

Sales of gas detectors and sensors:

portable and fixed gas detector for the detection of toxic gases (poison gas), corrosive, flammable, harmful and oxygen for use in industrial and laboratory safety and protection (laboratory)

Introduce

KQ series Fixed gas detector (also called gas sensor or gas transmitter). It can detect various gases such as flammable gas, O2、H2S、CO、HCN、NO2、SO2、NH3、HCL、CL2、H2 etc. Detector works 365 days.
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 Germany.

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 Imported sensor, high sensitivity, rapid response, stable and reliable

l operation is simple; easy installation and maintenance
