The Met One E-Sampler provides real-time particulate measurement through near-forward light scattering as well as filter loading capabilities for gravimetric measurement. Ambient temperature and pressure are measured so that an actual flow rate can be calculated. An all aluminum enclosure allows for use in conditions that other ambient particulate monitors can not tolerate.   Data is collected onto an internal logger and can be downloaded to a PC using the manufacturer’s software. PM10, TSP, PM2.5, and PM1 can all be measured with the correct inlet adaptor. Also available for rent from CleanAir Europe.
