Flue gas dust and opacity monitor
D-R 290
DURAG
* Allows calibration to measure the dust concentration in mg/m3
* Measures opacity and/or optical density
* Can be used even at thick-walled stone / insulated ducts
* Device is not in contact with sample gas
* Automatic zero and reference point check
* Automatic measurement and correction of soiling of optical windows
* Super-wide band diode (SWBD), long life, reduced influence of variable particle sizes
* Hermetically sealed enclosures - no flue gas diffusion to optics or electronics unit
* Optimized purge air reduces pollution, provides long maintenance intervals
* Heated optical window
* Easy installation, adjustment and maintenance, no PC required
* Local control unit displays opacity, extinction or mg/m3 values
* Additional display unit as an option in up to 1000m distance
