Description

 

Product Overview

KQ500D-CO is fixed gas detector (also called gas sensor or gas transmitter), can continuously detect the carbon monoxide concentration in the operating site. Adopts imported combustible sensor, with high sensitivity and repeatblility.

    Standard 4~20mA two wires signal output or rs485 output. It can transfer data in long distance, can communicate with DSC system directly. 

 

 

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
