STACKGUARD




Dust Concentration Monitor for Hot Gasses

The StackGuard continuously monitors the scatted light intensity of an extracted, withdrawn sample of gas. The laser light source minimized stray light and improves sensitivity to the µg/m³ level, the filtered purge air prevents from window soiling. A calibration check is performed by means of a checking rod.







  • Monitoring of hot gases in individual setup for facilities not under directives 2000/76/EC and 2001/80/EC

  • Continuous measurement of particulate matter concentration via scattered light principle

  • Automatic zero and span drift check and adjustment
