Födisch - Model OPM 19 ED -Dust Concentration Measuring Device

The measuring gas is sampled by a temperature-controlled probe, conveyed to a measuring cell and continuously diluted and dried with hot and dust-free ambient air. The dust measurement is based an optical scattered light measurement. Thereby the device is streamed with the measuring air and the dust content is measured by the optical sensor. In the electronics of the device the measuring signal is converted to an equivalent dust signal.
