D-RC 120便携式粉尘仪

red

     The D-RC 120 is an automatic sampling device for gravimetric dust measurements to adjust or calibrate dust monitors for the measurement of dust in mg/m3.

D-RC 120便携式粉尘仪

     The D-RC 120 extracts isokinetically a partial gas stream from the measuring gas duct whereas the extraction is controlled fully automatically. The partial gas stream is sucked through a filter in which the contained dust is deposited. The dust concentration is determined by weighing the filter before and after the extraction.

     The design of the D-RC 120 meets the requirements of DIN EN 13284-1 and US-EPA Method 5.
