Flue gas analyzer GasTDL-3001

stack gasammoniafor monitoring gas emissions

Product Description
GasTDL-3001 is an in-situ extractive tunable diode laser absorption spectroscopy (TDLAS) gas analyzer for real-time measurement of NH3 and HCl in flue gas. The unit mounts directly on the stack and uses a heated, in-situ extractive sampling path to prevent adsorption and loss of acidic and ammonia species, ensuring representative samples and fast response. Full-path calibration capability secures long-term measurement accuracy for flue gas cleaning control and environmental emission monitoring in power generation, chemical and metallurgical industries.
