As a high volume cascade impactor the series TE-230 provides a simple, accurate, and yet low-cost means of obtaining the particle size distribution and respirable mass fraction of suspended particulates in outdoor and occupational environments. The unique slotted impactor design features the ultimate in precision, predictability, and sharpness of cut-off, combined with compactness, ease-of-use, and the lowest internal losses.
