7. Specifications
The Dust Profiler uses a Met One Instruments Inc. 9722-1 OEM Particle Counter which operates on
the principle of light scatter from suspended particulates to provide a continuous real time
measurement of airborne particulate. An algorithm is then used to calculate the equivalent mass
concentration. More detailed specifications are in the table below.
