The DA60 utilises PCME’s unique Electrodynamic® measurement

principle. When the sensing probe is installed in the duct or stack, particles

in the air stream interact with the sensing rod and a charge induction affectis analysed from the probe. Distributions in the particle stream result in afrequency charge induction response, which is directly proportional to theconcentration of particulate. Unlike Triboelectric systems the measurementis not affected by build up on the probe, which can cause zero andcalibration drift. Very Low Dust concentrations can also be measured dueto this unique Electrodynamic® technique.
