Inside the Particulate Monitor – Optical Methods

At least two different optical techniques can be applied to measure the concentration of particulates – light absorption and light scattering. Light absorption is frequently used in high-concentration industrial processes, but it has some applications also in ambient air, for example to determine visibility at airports. Light scattering is utilized both in industrial and ambient ...
