Durag D-R 808 Dust Monitor

Industries: Stack, Process & CEMS
Categories: Manual & Automatic Stack Testing Equipment,
Brand:

The DURAG D-R 808 is a suitability-tested scattered light dust monitor for monitoring small to medium dust concentrations in dry flue or process gases.

With its certification range of 0 … 7.5 mg/m3 the D-R 808 is ideally suited for monitoring very low dust concentrations.

Key Benefits

  • Certified for official emission monitoring – QAL1 certified according to EN 15267-3, compliant with the requirements of US-EPA PS-11
  • Lowest certified range 0 … 7.5 mg/m3 – Reliable measurement of very low dust concentrations
  • Space-saving and easy installation – One-sided installation without alignment
  • Durable through integrated purge air monitoring – Protection of the device through continuously monitored purge air supply
  • Low maintenance effort – Linearity check with reference filters without removing the device from the stack (if stack pressure is negative)
  • Reliable emission monitoring – Automatic control functions ensure reliable measuring values
  • One-sided installation without optical alignment
  • Automatic zero and reference point check
  • Automatic contamination check and correction
  • Integrated purge air monitoring

Applications

Continuous emission monitoring, for example, in the following industries:

  • Waste incineration
  • Cement industry
  • Power industry
  • Wood industry
  • Chemical industry
  • Steel industry

Process monitoring, e.g.:

  • Monitoring of filter plants
  • Monitoring of ventilation systems
