Features Of Gas Analysis Equipment

The gas monitoring instruments manufactured by continuous emission monitoring system suppliers like ZETIAN are tools for gas leakage concentration detection. It mainly uses gas sensors to detect the types of gases present in the environment.
All sensors used to detect gas composition and concentration are called gas analysis equipment, regardless of whether it uses physical methods or chemical methods. For example, sensors that detect gas flow are not considered gas sensors, but thermal conductivity gas analyzers are important gas sensors, although they sometimes use generally the same detection principles.

TDLAS (Tunable Diode Laser Absorption Spectroscopy) mainly uses the character that tunable laser's narrowband and wavelength change with the current. So by precisely modulating the current of tunable laser, it can scan a certain absorption peak of detected gas (no absorption of background gas). And after obtaining the second harmonics absorbed by detected gas, it finally works out the concentration of detected gas by using this second harmonics and line-width. 

Gas Analyzer Supplier

ZETIAN, a gas analyzer supplier, offers high-quality multi gas analyzers such as LGT series, portable ftir analyzer and online gas analyser. By using a tunable semiconductor laser, LGT series laser gas analyzer scans the specific absorption lines of the measured gas (no background gas) to get the second harmonic of the gas. Through processing and analyzing the second harmonic and the broadening information of the gas, the concentration of the gas is obtained.

Our continuous gas analyzers are widely used in petrochemical, chemical, coal, electricity, automobiles, air purification, building HVAC, medicine, food, environmental protection, telecommunications, home appliances, metallurgy, municipal gas, environmental monitoring and many other fields. It can also perform gas concentration detection or leak detection on tunnels, pipelines, tanks, enclosed spaces, etc., to meet the measurement needs of special occasions.
