IGAS 100 sulfur dioxide analyzer is a gas analyzer product for dilution measurement in ambient air quality monitoring and continuous emission monitoring system (CEMS). It is based on the technical principle of ultraviolet fluorescence method. Combined with advanced microprocessing technology, it provides accurate and reliable measurement and analysis of SO2 at nmol/mol~umol/mol(ppb~ppm) level.
· This product has the characteristics of high measurement accuracy, good reliability, fast corresponding time, easy operation and wide application range.
· The analyzer supports manual calibration and automatic calibration, the calibration procedure can be set by the user, and supports remote control and remote upload.
· Real-time measurement data and instrument status parameters can be automatically transmitted and queried, which can facilitate relevant departments to timely and accurately grasp the air quality status.
