Solutions - SO2 Monitoring

Sulfur Dioxide (SO2) is a criteria pollutant in power plants, incinerators, the cement industry and smelting processes as well as being used as a food grade preservative and must be monitored to ensure health and safety regulations.  In the cement industry it is also monitored for process control.

The Unisearch Differential Optical Absorption Spectrometer (DOAS) offers a perfect solution for SO2 monitoring.  It ensure accurate and rapid response to SO2 levels in in both cross stack and extractive measurement configurations.  The Unisearch DOAS provides:

  • Reliable, accurate data
  • Rapid response – 10’s of seconds if desired
  • Continuous emissions monitoring of SO2 levels
  • Correction of interferences by other gases which could result in erroneous data
  • Easier maintenance and improved process control
