LGT-450 Flue Gas Analyzer is a highly integrated single-flange gas monitoring equipment, of which, core detection module adopts Tunable Diode Laser Absorption Spectroscopy (TDLAS) and Differential Optical Absorption Spectroscopy (DOAS) gas absorption technology with independent intellectual property rights. The specially designed measuring cell effectively improves optical path length for gas absorption, which can measure trace gas accurately inside pipeline. One equipment can realize online monitoring for multiple gas components, such as CO, CO2, SO2, NO, NO2, etc.
Features
Filter element can be easily disassembled and replaced.
Adopt single-flange design with high integration and easy installation.
With high-temperature flowmeter, user can observe flow during equipment operation.
Sampling measurement is free from interference of pipeline deformation, high dust and other working condition change, with strong adaptability.
The whole gas path is equipped with high-temperature heat tracing and regular auto purge to prevent dust and crystal like salt from blocking the equipment, less maintenance.
Application
Applied in online gas monitoring occasions including denitrification device, boiler flue and exhaust detection, etc.
