BLA-LGT-200 laser gas analyzer (in-situ type)

• brief introduction

The BLA-LGT-200 laser gas analyzer is a flameproof in-situ probe type tunable laser gas analyzer developed by the company for industrial online analysis and environmental online monitoring at home and abroad. It can analyze various gases including O2, CO, NH3, CO2, CH4, H2O, HCl, HF, HCN, etc. online under various complex working conditions (note: a single analyzer can only analyze 1-2 components), and the measured gas concentration ranges from constant to trace.

• characteristic

       Adopting in-situ measurement without the need for a preprocessing system, avoiding problems such as sample adsorption, blockage, and device damage during preprocessing;

       Adopting an integrated structure with no moving parts, it has good reliability and stability;

       Using "single line spectroscopy" technology to measure without interference from background gas crossing;

       The optical path achieves non coupled direction adjustment, making on-site optical path adjustment simple.

• application

Analysis of gas recovery from converter gas; Analysis of circulating gas in dry quenching process; Oxygen analysis of coke oven gas after electric coke capture; Analysis of coal injection gas in blast furnace; Analysis of ammonia escape gas in the cement industry; Trace CO detection and analysis in industries such as electricity, cement, and environmental protection; Trace HCl and HF analysis in industries such as environmental protection and chemical engineering.
