Product Introduction
The GWD31 fixed gas detector is a gas sensor dedicated to the measurement of gas concentrations in the air. It uses a catalytic combustion sensor or an electrochemical sensor. Concentration data sampling from 0000 to 9999 digital display mode, intuitive understanding of the concentration status. Built-in microcontroller and software linear temperature compensation algorithm. It can realize on-site one-person calibration. These global products are certified explosion-proof in various countries and meet the requirements of various international standards, including CE and SIL 2 certification.
