Personal Modular Impactor (PMI), PM2.5, 3 L/min
Personal Modular Impactor (PMI), PM2.5, 3 L/min Overview
Personal Modular Impactor (PMI), single-stage impactor designed for highly efficient collection of PM2.5 at 3 L/min, includes impactor and filter cassette with support screen; requires collection media and impaction substrate, which are purchased separately The PMI closely follows PM2.5 as defined by EPA.
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.
