TE-230 High Volume Cascade Impactor
The Series TE-230 provides a simple, accurate, and 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.
