Description
Overview
GAOTek chlorine gas detector is a fixed gas detector (also called gas sensor or gas transmitter), which can continuously detect the CL2 concentration in the operating site. Adopts imported electrochemical sensor, with high sensitivity and repeatability. Standard 4 mA to 20 mA two wires signal output or RS 485 output. It can transfer data over long distances, can communicate with DSC system directly.
