ZFDM-4 Flue Gas Dust Monitor

Robust and accurate back scattering dust monitor for rough industrial installations

QAL1 certified continuous monitoring of particulates concentration. Thanks to the backscattering technology, the LED light beam provides an accurate measurement (insensitive to ambient light).

The self-checking anti-fouling functions and the continuous automatic correction system correct possible measurement drifts. This device is suitable for small and medium diameter ducts, for very low and medium dust concentrations as well as for light to dark coloured particles.

Applications

Continuous particulates emissions monitoring
Coal, biomass, and other solid fuels fired boilers
Oil fired boilers, diesel engines
