Aerosol Diluters

When using a particle counter for filter integrity testing, filters and filter systems are typically challenged with an excess of six million particles per cubic foot of air (2.1×108 per cubic meter). Most particle counters are capable of only counting up to 100,000 particles per cubic foot of air before experiencing significant coincidence counting (counting two or more small particles as one larger particle). It is necessary to know the filter aerosol challenge concentration in order to properly quantify defects, thus a reliable aerosol dilution device is required. QVA Test Solutions offers a line of NIST traceable aerosol diluters to be used in conjunction with particle counters and other aerosol sampling systems.
