QGS-08C Ex infrared gas analyzer Introduction
QGS-08C / 08C Ex infrared gas analyzer is a non-spectral infrared gas analyzer, which is based on the principle of selective absorption of infrared light by certain gases. It adopts single light source, thin-film microphone detector in series absorption chamber, advanced all-digital signal processing technology, and new LCD display interface.
QGS-08C Ex infrared gas analyzer is used for continuous analysis of CO, CO2, SO2, CH4, NH3 and other gases in a variety of gas mixtures online.
QGS-08C Ex infrared gas analyzer products are widely used in:
Environmental monitoring such as air pollution source emissions;
Industrial control in petroleum and chemical industries;
Agriculture, medical health and scientific research fields;
Determination of gas content in various combustion tests in the laboratory;
Air quality monitoring in public places;
QGS-08C Ex infrared gas analyzer is mainly used in explosion-proof occasions controlled by petroleum, chemical industry and other industries. Features
