Quest EVM-3 Real-Time Direct Reading Particulate Monitor

The EVM-3 provides real-time direct reading of particulate mass concentrations along with temperature and relative humidity measurements. The proprietary dial-in impactors allow for quick selection of particulate settings PM2.5, PM4, PM10 or TSP (within the instrument`s measurement range) without disassembly.

A built-in air sampling pump assists in the collection of particulates while the laser photometer provides real-time measurement. A standard 25 or 37 mm gravimetric cassette can be utilized for sampling and laboratory analysis and help provide correlation for real-time direct reading measurements.
