Combustible Gas Toxic Gas Leakage Detector

 Gas Detector

1 Overview

        Point-type gas detector is new detection equipment, which combines high-performance catalytic combustion gas sensitive components and sophisticated SMD craftsmanship. The gas detector has good repeatability, good abilities of anti-interference and anti-wet temperature, and has long life. And it is easy to operate. Point-type gas detector can transform the signal of the gas concentration in the air to an electrical signal and pass the electrical signal away. It is with 4-20MA analog standard three-wire configuration. The detected result can be checked far away from the site through monitoring instrument or controller. This gas detector applies to variety of flammable industrial sites which require explosion-proof, gas poisoning prevention measures, such as gas pipe network, chemical industry, gas stations.
