IN-SITU Laser Gas Analyzer
In-situ type analyser is capable of analysing O2, CO, NH3, CO2, CH4, H2O, HCl, HF and other gases in various and complex conditions. The laser gas analyser can be directly installed across stack/ Duct, with the advantages of uncomplicated sampling, no pre-treatment system, simple construction and no moving parts.
