Product Overview
Description
KQ500D fixed h2s Hydrogen sulfide gas leak detector&alarm
Product Overview:
KQ500D series Fixed gas detector (also called gas sensor or gas transmitter) can detect various gases such as flammable gas, O2,H2S,CO,HCN,NO2,SO2,NH3,HCL,CL2,H2 etc., 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. Transform the gas density in the operating site into standard 4~20mA electric current signal and output the signal to the total controllors through two-core or three-core shield cable, so keep the signal with high fidelity. It 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.
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
