SO2 Monitoring in Air - Air and Climate - Air Monitoring and Testing
SO2 (sulfur dioxide) is measured in a number of applications. SO2 is used as a food grade preservative and must be regulated in accordance with government-set criteria to be safe for consumers. It is also measured in fuel exhaust to control for environmental pollution and in cement plants for process control.
Unisearch offers a perfect SO2 analyzer that fits each of these applications - the UV DOAS system. Studies have shown that the UV DOAS equipment provides data that is more accurate than conventional gas monitoring equipment. When calibrated for SO2 monitoring, UV DOAS gas monitoring equipment is able to detect SO2 among other gases present in the area and provide continuous updates with regards to the changes in its concentration.
