• 2 s resolution time• measures number and sizesimultaneously• weighs 5.5 kg• battery life approx 8 hrs• measures 20 … 200 nm• suited for fi eld studies• no technical experience necessaryto operateMany aerosol instruments are large, heavy,fragile and expensive. DiSC was designedto avoid these characteristics with the aimto offer an instrument suitable for fieldmeasurements where accuracy and sizedistribution are not critical elements. It isthe fi rst of its kind on the market.DiSC is a modifi cation of the well knowndiffusion charger (DC). Aerosol is chargedand then passes through 3 measurementstages.In the diffusion stage, smaller particlesare deposited by diffusion while passingthrough a series of stainless steel grids.In the induction stage, aerosol passesthrough unobstructed.During a rapid concentration change, acurrent is induced in both this stage and inthe diffusion stage and is corrected for.Lastly, the filter stage consists of particlesbeing collected on a fi lter.Sensitive current amplifi ers measure the3 currents (induction, diffusion and filter)and their signals are digitalized.A data analysis software calculates numberand size and sends this via Bluetooth orUSB to a PC or can be saved directly ontoan SD/MMC memory card.DiSC is approximately as large as twolaptop computers placed on top of eachother.The portability of DiSC requires minimalset-up fuss and allows the ease of carryingDiSC in the field, for example, ambient airstudies of aerosol number concentrationsin urban areas.
