The Met One Instruments 831 Aerosol Mass Monitor simultaneously provides data of four important mass ranges in one minute. Ranges include PM1, PM2.5, PM4, and PM10.

A portable monitor that can be worn on the belt for assessing dust exposures of workers at all workplaces. Air around the "breathing zone" is sampled.

Mass concentration ranges: PM1, PM2.5, Respirable ("PM4.5"), PM7, PM10 and TSP

Concentration range: 0 - 1000 microgram/cu.m

Real-time dust monitoring takes a giant leap forward!! Only the DustTrak™ DRX Aerosol Monitor 8533 can simultaneously measure both mass and size fraction - no other monitor can do both.
