LGT-450 flue gas analyzer Introduction: The LGT-450 flue gas analyzer is a highly integrated single flange gas monitoring device, with its core detection module using tunable diode laser absorption spectroscopy (TDLAS) and differential optical absorption spectroscopy (DOAS) gas absorption technology with independent intellectual property rights. The specially designed measurement cell effectively improves the optical path length of gas absorption, which can accurately measure trace gases in the pipeline. A device can achieve online monitoring of various gas components such as CO, CO2, SO2, NO, NO2, etc. Applied in online monitoring of flue gas, including denitrification devices, boiler flue gas detection, etc. Features: 1. The filter element can be easily disassembled and replaced. 2. Adopting a single flange design, with high integration and easy installation. 3. By using a high-temperature flow meter, users can observe the flow rate during equipment operation. 4. Sampling measurement is not affected by changes in working conditions such as pipeline deformation and high dust, and has strong adaptability. 5. The entire gas pipeline is equipped with high-temperature tracing and regular automatic blowing to prevent dust and crystalline salt from blocking the equipment and reduce maintenance.
