DT-04 Gas Detector

Product Overview

DT-04 series gas alarm monitor is a two-wire, three-wire 4-20mA analogue signal or RS485 bus output fixed gas detection probe developed by our company, which adopts imported gas sensors and has the features of short response time, high accuracy, stable operation and strong anti-interference.

It can be connected with various types of detecting controllers produced by our company such as POLYMCS series, DK series, etc. It can also be directly connected to the DCS or PLC system on site to realise the monitoring, alarming and controlling of hazardous gases in the production environment.The DT-04 series of stationary gas transmitters can detect more than twenty kinds of gases and have a high cost performance, which can be applied in metallurgy, petroleum, chemical industry, metallurgy, petroleum, chemical industry, fire fighting, electric power, industrial and mining, municipal and other industries, gas monitoring in a variety of places.
