Dust Emission Analyzers
Dust Emission Analyzer is a stationary or portable instrument for measuring suspended particulates in a liquid or gascolloid. It measures suspended particulates by employing a light beam (source beam) and a light detectorset to one side (often 90°) of the source beam. Particle density is then a function of the light reflected into the detector from the particles. To some extent, how much light reflects for a given density of particles is dependent upon properties of the particles such as their shape, color, and reflectivity.
Dust emission analyzers are calibrated to a known particulate, then use environmental factors k-factors to compensate lighter or darker colored dusts accordingly. K-factor is determined by the user by running the dust emission analyzer next to an air sampling pump and comparing results.
