LFR-6 Sampler

The Low Flow Research Sampler is a portable, rapidly deployable, battery-powered particulate sampling device. It utilizes FRM-style impactors for improved accuracy at 6 LPM and requires no grease or oil for low maintenance use. The compact-sized sampler can be configured to collect 24-hour TSP, PM10, or PM2.5 filter samples and can simultaneously measure and log all real-time sampling parameters, meteorological data, and particulate counts.

The Low Flow Research Sampler can be equipped with an optional PEET anemometer and is capable of operating in directional sampling mode. It can also be equipped with a Plantower light scattering sensor to log temporal particulate variations. All sampling parameters, meteorological data, and particulate data are logged at
5-minute intervals and can easily be accessed via USB flash drive.
