In line with regulatory developments, we now offer you our analyser Fuji ZFDM-4 dust monitor.
This device retains its ease of installation, with its one-piece sensor suitable for a wide range of applications (coal, fuel oil, biomass, other solid fuels).
Self-monitoring for clogging and automatic continuous correction correct any measurement drifts.
The device is suitable for small to medium duct diameters, for very low to medium dust concentrations and for light to dark-colored particles. Electronic chopping of the LED beam ensures insensitivity to ambient light.
