Adopting advanced Ultraviolet Differential Optical Absorption Spectroscopy (UV-DOAS) technology, the LG-1103P portable flue gas analyzer is a high-precision, highly stable detection device for flue gas emission monitoring. It performs real-time concentration measurement of multiple industrial flue gas components including SO2, NO, NO2, CO, CO2 and O2, and automatically calculates emission parameters. Featuring compact portability and intuitive operation, the instrument supports automatic sampling, analysis and data processing, making it ideal for on-site rapid detection. It delivers reliable data to support environmental supervision and industrial process control.
· High-precision UV spectroscopy: Built on proprietary UV-DOAS algorithm with strong anti-interference capability to guarantee accurate, consistent measurement results
· Portable ergonomic design: Lightweight construction suitable for field, outdoor and high-altitude operation scenarios
· Wide environmental adaptability: Equipped with a high-capacity built-in battery, supporting both wired mains power and fully wireless battery operation to accommodate most working conditions
· Simultaneous multi-gas detection: Synchronously measures SO2, NO, NO2, CO, CO2, O2 and other customizable parameters
· Intelligent & efficient workflow: Intuitive touchscreen interface with real-time data storage, export and Bluetooth data transmission functions
· Low lifecycle maintenance cost: Calibration-free optical module, long service-life sensors and simplified maintenance procedures
