Page 6: System Overview
Dust Detective System Overview The complete system (Part number 206107A) would require the purchase of the static air sampling enclosure (Part number 206200D), plus the following additional items:- • Microdust Pro, • Apex2ISPlus air sampling pump and charger • Pre weighed GFA filters – if gravimetric analysis is required •... - Page 7 Dust Detective Due to the light scattering principle used within the instrument, any moisture which individual particles attract at periods of high humidity or temperatures approaching “dewpoint” will be “seen” by the instrument as larger particles. This biases results towards greater concentrations. Also, during these periods, any air being drawn through the instrument which is high in humidity may condense on the optics and distort the light beam, producing spurious results.
