KQ500 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 China.
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
