Model No. APM 550 - PM2.5 / Samplers APM 550
Recent studies sponsored by USEPA have concluded that Fine Particles, (PM2.5) which penetrate deep into the lungs, are more likely to contribute to health effects. Fine Particulate Matter (FPM) also adversely affects visibility. In keeping with Envirotech’s tradition of anticipating the need and pioneering development of suitable indigenous instruments the APM 550 Fine Particle Sampler has been developed. The APM 550 system is a manual method for sampling fine particles (PM2.5 fraction) and is based on impactor designs standardized by USEPA for ambient air quality monitoring.
