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) |
IntroduceKQ 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. |
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 |
