The FW102 is designed for continuous measurement of low to medium dust concentrations - independent of the gas velocity, humidity, or charge of the particles. The probe design of FW102 enables mounting on one side of the gas duct and does not require any mechanical adjustment or calibration with a dust-free measurement path.
