Measurement of dust concentration at emission
Fields of application
Continuous monitoring of particulate emissions, coal-fired boilers, biomass and other solid fuels, oil-fired boilers, diesel engines.
Benefits
In line with regulatory changes, we are pleased to offer our Fuji ZFDM-4 dust analyser .
This device remains easy to install, featuring a one-piece sensor suitable for a wide range of applications (coal, fuel oil, biomass, and other solid fuels).
The self-monitoring for clogging and continuous automatic correction functions correct any measurement drifts.
The device is suitable for small- to medium-diameter ducts, for very low to medium dust concentrations, and for particles ranging from light to dark in color. The electronic chopping of the LED beam ensures immunity to ambient light.
