The UV-DOAS-500P is our independently developed portable flue gas analyzer, engineered for precise online gas analysis in environmental protection and industrial control applications worldwide. Leveraging advanced Ultraviolet Differential Optical Absorption Spectroscopy (UV-DOAS), this compact instrument delivers fast, reliable measurements of multiple gas components—including SO₂, NO, NO₂, O₂, CO, and CO₂—in a single, field-ready unit.
Multi-Component Analysis: Measures SO₂, NO, NO₂, O₂, CO, and CO₂,CH4 simultaneously for comprehensive flue gas profiling.
Integrated Flue Diagnostics: On-board sensors record flue temperature, pressure, flow velocity, and sampling velocity—enabling accurate calculation of excess air coefficient and pollutant emission rates.
High Accuracy & Stability: Exceptional measurement precision with minimal drift and rapid response time- ideal for both routine inspections and urgent troubleshooting.
Full UV-Spectrum Measurement: Electronic scan across the ultraviolet spectrum without moving optical parts—eliminates mechanical wear, reduces maintenance, and guarantees consistent performance.
Robust Gas Compatibility: Low requirements for sample gas conditioning; operates effectively in high-dust environments without the need for complex filtration.
