PPM Level Ambient Air Quality Monitoring Instruments for SO2 Concentration Detection
Product Introduction
The SO2 Ambient air quality monitoring instruments is an analyser based on UV fluorescence technology and can detect SO2 concentrations at ppb~ppm levels. It is one of the important analysers for ambient air quality monitoring systems and is used to detect SO2 concentration levels in ambient air quality parameters.
Product Performance
1. Color screen display and touch screen operation.
2. With environmental parameter compensation function.
3. Adaptive filtering to optimize response time.
4. Supporting remote calibration and parameter diagnosis.
5. Built-in memory for storing three months of average data.
