SKC (environmental measurement) Personal Modular Impactor (PMI) Impaction Substrate (Pre-oil treated, 25 sheets)

These are pre-oil-treated porous plastic discs, used as impact substrates for PMI samplers. They are 25 mm in size, ready for use, and are disposable; they are essential for sampling with a Personal Modular Impactor (PMI).
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.
