Product OverviewGasTDL-3001 is an in-situ extractive TDLAS gas analyzer for real-time measurement of NH3 and HCl in flue gas. Based on Tunable Diode Laser Absorption Spectroscopy (TDLAS), it provides highly selective, low-interference measurements and fast response tailored to CEMS and process control in industrial exhaust systems.
GasTDL-3001 uses an in-situ extractive configuration with the measurement unit mounted on the stack to minimize sample transport and response delay. The extracted gas path is heated and made from low-adsorption materials to prevent NH3 and HCl adsorption or condensation, preserving sample integrity. Full-path calibration capability ensures long-term measurement stability and suitability for flue gas cleaning control and emissions monitoring in power generation, chemical and metallurgical plants.
Segment / DivisionSegment: Flue Gas Analyzer
Division: Continuous Emission Monitoring System (CEMS)
Features- Anti-interference measurement: TDLAS enables highly selective detection of target gases with minimal cross-interference from background components.
- High accuracy: Full-path calibration maintains measurement accuracy over time.
- Ultra-low detection range: Multi-pass optical cell extends path length for low detection limits.
- Zero sample loss: Heated sample line with low-adsorption materials prevents NH3 and HCl loss by adsorption or condensation.
- In-situ extractive method: Sample drawn from the duct while minimizing effects of in-duct dust, temperature and pressure fluctuations.
- Easy installation: Compact construction adaptable to various site configurations.
