Zetian - Model LGT-300 -Single-side Laser Gas Analyzer
The LGT-300 is a high-precision gas analyzer developed based on Tunable Diode Laser Absorption Spectroscopy (TDLAS), and can realize in-situ single-end measurement of gas concentration. The analyzer can online analyze multiple gases including O2, CO, NH3, H2S, CO2, N2O, HCN, H2O, etc. In addition, it can achieve the online calibration function of any other gases except H2O.Single-ended measurement: no need for complex adjustments of the optical path;
Single-line spectrum technology: free from cross interference of background gases;
In-situ measurement: with no need for a pretreatment system to avoid sampling adsorption,
blockage and component damage in preprocessing, reducing operation cost.
Exhaust monitoring and process control in waste incineration plants, coal fired power plants, cement plants, glass factories, ceramic factories, sintering, coke oven, Desulfurization Technology and Denitration Technology, etc.
