The DustScan DS100-D is a combined directional and deposited dust sampler. The unit combines the DS100 sticky pad directional dust gauge with the DustDisc dust settlement gauge by replacing the standard DS100 rain gauge with a DustDisc holder and bird-strike guard.
The directional and deposited dust sampler collects dust in horizontal flux from 360° around the sampling head as well dust depositing out of the air. The DustScan DS100-D can be used for monitoring on site boundaries or at receptors. The collected dust is measured using DustScan’s unique software to determine dust coverage (AAC) and dust soiling (EAC); these measurements are expressed as percentages and are noted in IAQM guidance. Subsequent analysis can be used on the DustDisc to determine the mass of material and calculate the dust deposition rate. If required, deposited or fugitive dust may be further investigated using microscopic or other analytical methods.
Sampling periods should be regular and uniform in order to deduce useful information.
