3M EVM-3 Environmental Monitor
Ambient Air Monitor

The EVM is a portable-area monitoring instrument using a selectable impactor with four settings: 2.5 μm, 4 μm, 10 μm, or none (100 μm). Once the impactor setting is selected, the EVM collects (or measures) real-time aerosol/dust concentrations using a 90º optical light scattering photometer to determine the total mass concentration (in units of mg / m3) of particulate matter. Additionally, gravimetric sampling, a more accurate method, can also be used. The unit can be operated for 8 hours using an internal rechargeable battery.
