N100 – UV Fluorescence SO2 Analyzer
เครื่องตรวจวัดก๊าซซัลเฟอร์ไดออกไซด์
The Model N100 instrument uses the proven UV-fluorescence principle, combined with a state-of-the-art modular architecture, and intuitive operating software to provide accurate and dependable measurements of low-level Sulfur Dioxide (SO2) gas.
The instrument’s UV light source is continuously flashed to provide exceptional stability and long lifetime. Any potential lamp intensity fluctuations or detector drift is automatically managed in real-time using a sophisticated combination of reference readings during the lamp light/dark cycles. Hydrocarbon gases that fluoresce at the same wavelength as SO2 gas are removed from the sample stream through a scrubber (i.e. kicker) and prior to detection to eliminate any potential interferences. The long-life sample filter option further improves efficiency with a ~6 month exchange interval in ambient air quality monitoring applications.
