LFR-6 Sampler

The LFR-6 (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 fully battery powered. It can simultaneously measure and log all real-time sampling parameters, meteorological data, and particulate counts.

The LFR-6 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.
