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
