Sulfur Dioxide (SO2) Sensor Module

The Sulfur Dioxide sensor module can measure ppb level accurate concentrations of SO2 in ambient conditions. The sensor module design is capable to monitor sulphur dioxide emissions from point sources on a real-time basis.

Advanced support electronics are developed to sense even very low concentrations of gas. Strong signal levels combined with low zero current allows very low concentration detection (<10 ppb) and a wide operating range. Additionally, the low noise electronics produces stable signal resulting in high accuracy even with low concentration atmosphere. The SO2 sensor works on the electrochemical principle. Electrochemical sensors are very sensitive to SO2 gas changes, which makes it an ideal choice for indicative air quality monitoring for outdoor applications. Standard calibration gases and tools are used to calibrate the SO2 sensor modules. The calibration is in accordance with the USEPA (40 CFR Part 53) and EU (2008/50/EC) defined for equivalent method instruments. outdoor air quality monitoring system like Polludrone Smart and Polludrone Pro use the SO2 sensor module. Our Odour monitoring system like Odosense Lite, Odosense Smart, and Odosense Pro also include this sensor module. This module is ideal for applications like smart cities, industries, airport monitoring, tunnel monitoring, roadside monitoring and research projects.
