PMI Calibration Adapter Overview

PMI Calibration Adapter, for use with Personal Modular Impactor (PMI), ea

The SKC Personal Modular Impactor (PMI) Samplers are highly efficient for personal PM10, PM2.5, or PM Coarse (10-2.5) sampling and closely follow the PM2.5 and PM10 criteria defined by U.S. EPA. PMI Samplers are lightweight and compact with a convenient removable filter cassette and disposable pre-oiled impaction discs (no cleaning or greasing). The PMI PM10 model is easily converted with an accessory ring to sample PM Coarse (10-2.5). Use PMI Samplers with any constant flow pump at 3 L/min. SKC recommends the AirChek XR5000 Sample Pump.

SKC Personal Modular Impactors
The patented (U.S. Patent No. 7,334,453) SKC Single-stage Personal Modular Impactors (PMIs) are designed for the highly efficient collection of PM10, PM2.5, or PM Coarse (10-2.5). The samplers are easy to use with their removable filter cassette and pre-oiled impaction disc. PMI media changes are as easy as removing the filter cassette and replacing it with one already loaded with a 37-mm final filter. The 25-mm pre-oiled impaction disc mounts directly on top of the filter cassette and reduces particle bounce for high collection efficiency. A 25-mm filter may be used as an alternative impaction substrate for gravimetric or chemical analysis of particles. The PMI Coarse model and the Coarse Ring accessory include a second filter cassette to allow collection of particles sized between 2.5 and 10 µm.
