D-RC 120便携式粉尘仪
本帖最后由 red 于 2016-9-2 14:47 编辑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. 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.Overview
