BLA-LGT-800 laser gas analyzer (disk mounted)

• Introduction

The BLA-LGT-800 laser gas analyzer is a disk mounted tunable laser gas analyzer developed by the company for industrial online analysis and environmental monitoring at home and abroad. The core of the instrument uses a White cell to achieve optical path reversal, with an optical path length of up to 25m and a low detection limit. Multiple gases including O2, CO, NH3, CO2, CH4, H2O, HCl, HF, HCN, etc. can be analyzed 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.

• feature

19 inch 3U disk mounted chassis, compact structure, easy to integrate;

Using TDLAS technology, the interference of background gas crossing has been eliminated;

By using multiple reflection optical path technology, the maximum measured optical path length can reach 25m, significantly improving the detection limit level;

High reliability without optical moving parts, and on-site vibration has no impact on measurement.

• application

Gas analysis of metallurgical steelmaking furnace; Petrochemical refining; Urea chlor alkali manufacturing process gas.
