3. StackGuard system
Dust Emission Measuring System.
  • The tried-and-tested measuring system for tough jobs, e.g. continuous monitoring of tiny concentrations in dry or wet and hot gases
  • Continuous measurement of particulate matter concentration via scattered light principle
  • Compliance with EN 14181
  • Automatic zero and span drift check and adjustment
  • Easy adjustment with checking rods
  • Highest sensitivity in range m/Nm
  • Certainty that neither the ring pipe nor the flow cell will become contaminated
  • Freedom from condensation, thus avoiding falsified readings and material wear
