The MiniVol LFR (Low Flow Research) Sampler is the newest generation of the Airmetrics MiniVol, with improved accuracy and data logging for air quality researchers.

The MiniVol LFR is a portable, rapidly deployable, battery-powered particulate sampling device. It uses 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 MiniVol LFR uses FRM-style impactors and a PM2.5 cyclone for improved accuracy and requires no grease or oil for low maintenance use.

The MiniVol LFR Sampler can be upgraded with an optional wind sensor to collect air samples based on wind direction. It can also include a sensor that uses light to measure changes in dust and particle levels over time. The device records all sampling details, weather data, and particle readings every 5 minutes. All this information can be easily saved and viewed using a USB flash drive.

It can be equipped with an optional wind sensor and is capable of operating in directional sampling mode.

Directional sampling mode is when an air quality monitor collects air samples based on the direction the wind is blowing. Instead of just pulling in air from all around, the sampler uses a wind sensor (anemometer) to only collect air coming from a specific direction.

Why this matters:

• It helps identify sources of pollution, like figuring out if dust is coming from a construction site, road, or factory in a certain direction.
• Useful for environmental studies near specific pollution sources (e.g., mines, landfills, industrial areas).

It can also be equipped with a Real-Time Particulate Profiler, which uses a light scattering sensor to log PM2.5 and PM10 concentrations.

All sampling parameters, meteorological data, and particulate data are logged at 5-minute intervals and can easily be downloaded via USB flash drive.
