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.
Continuous emission monitoring, for example, in the following industries:
Process monitoring, e.g.:
Flue gas type | Air, flue gas, non flammable process gas |
Flue gas temperature | Above dew point up to +350 °C optional up to 500 °C with additional components |
Inner duct pressure | -50 … +50 hPa |
