The optical dustanalyser provides continuous and highly accurate measurement of particles in industrial flue gas. Based on the backscattering of an LED beam, it monitors atmospheric emissions while ensuring that facilities comply with regulations.Designed for small- and medium-diameter ducts, this analyser offers excellent sensitivity, even for very low dust concentrations. Its automatic fouling compensation system, self-diagnostic functions, and ambient light-insensitive measurement ensure long-lasting performance in the most demanding industrial environments.Fuji Electric’s optical dust analysers s are particularly well-suited for monitoring emissions from boilers, furnaces, and combustion facilities. Certified to QAL1 standards, they meet CEMS system requirements and enable reliable monitoring of particulate emissions while reducing maintenance needs.

ZFDM-4 flue gas dust analyser

analyser Fuji Electric dust sensor with a control box connected to a remote sensor

analysers A robust and reliable backscatter dust monitor for demanding industrial applications. QAL1-certified system for continuous measurement of particle concentration. Thanks to backscatter technology, the LED light beam provides accurate measurements (unaffected by ambient light). The self-monitoring anti-clogging functions and the continuous automatic correction system correct any measurement drifts. This device is suitable for small- and medium-diameter ducts, for very low to medium dust concentrations, and for particles ranging from light to dark in color.
