    "abstract": "GRIMM 1.108 dust monitor run by the University of Manchester measures the size resolved number concentration per cubic centimetre of particles in the size range of 0.3 to 20 microns (optical). By summing up the total number over all sizes, the total number concentration can be derived. The unit also has several audible alarms when operational parameters are exceeded. The unit is mains powered, but also comes complete with a battery. The unit is completely controllable from the front panel, although data logging is normally done via a PC.\r\n\r\nThis instrument measures the size resolved number concentration per cubic centimetre of particles in the size range of 0.3 to 20 microns (optical).
