SKC (environmental measurement) Personal Modular Impactor (PMI) Coarse Ring

This is a Coarse Ring for Personal Modular Impactors (PMI), including a filter cassette and retainer, and is an accessory for converting a PMI 10 to a PMI Coarse Impactor.
The SKC Personal Modular Impactor (PMI) sampler offers high efficiency in sampling PM10, PM2.5, or PM Coarse (10−25) for personal exposure measurements and complies with the US EPA standards for PM2.5 and PM10. The PMI sampler is lightweight and compact, featuring an easily removable filter cassette and disposable, pre-oiled impaction discs that require no cleaning or greasing. The PM10 model of the PMI can be easily switched to sampling PM Coarse (10−25) using an accessory ring. The PMI sampler is used with a constant flow pump operating at 3 L/min, and SKC recommends using the AirChek(R) XR5000 Sample Pump.
