The D-RC 120 automatic sampling device for gravimetric dust measurements adjusts or calibrates dust monitors for the measurement of dust in mg/m3.
The D-RC 120 extracts isokinetically a partial gas stream from the measuring gas duct while the extraction is fully controlled automatically. The measuring process can be described as follow; the partial gas stream is sucked through a filter in which the contained dust is deposited. Then, the dust concentration is determined by weighing the filter before and after the extraction. In parallel to the gas sampling, the measurements of the dust monitor under test can be recorded and averaged. The D-RC120 has been design for different applications such as calibration of dust monitors and control measurements and measurement at filter plants. This device can also be conveniently operated via computer software.
