Inside the Particulate Monitor – the Triboelectric Method

We’ve seen in previous blog posts that particulate concentrations can be measured by filter-based techniques as well as by some different optical methods. However, it doesn’t stop there. Let’s also have a look at a principle based on the electrical charges of particles – the triboelectric method.
