Product Overview

KQ500D 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, 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.

 

 

Main Features:

Various kinds of gases detectors, high precision

Fixed explosion-proof shell, safe and reliable

4~20 mA electric current output, compatible with existing alarm unit or DCS ( distributed control system)

Imported sensor, sensitive, high precision, quick response, stable performance

Sipmple operation steps, easy to install and maintance

Detect and analyze gases concentrantion in remote places
