Personal environmental monitors

The Model 200 Personal Environmental Monitor is a lightweight personal sampler for collecting airborne particles in the PM2.5 and PM10 size ranges. PM2.5 and PM10 particles are airborne particles less than 2.5 and 10 µm, respectively. They are frequently used to provide a measure of airborne particle concentration for studying potential health effects of airborne particles in the indoor or outdoor environment.

The aerosol sample enters the Model 200 through a multi-nozzle, single-stage impactor to remove particles with aerodynamic equivalent diameter larger than 2.5 or 10 µm in diameter. Particles smaller than the impactor cut-size are collected on a 37 mm diameter filter of choice. The collected particles can be analysed gravimetrically to determine the airborne particle mass or analysed for specific chemical compounds.

Features include: lightweight, personal sampler with single-stage impactor and final filter; impactor cut-point of 2.5 or 10 µm; and can be operated with a personal sampling pump.

Applications include: personal PM2.5 or PM10 sampling for exposure assessment; indoor/outdoor air pollution studies; indoor/outdoor air quality assessment eg, mine sites; and personal sampling for industrial hygiene applications.
