The DUSTHUNTER SB30 is a measuring device for detecting low and medium dust concentrations, e.g., in hot or aggressive gases. The measurement is based on the proven measurement principle of backward light scattering. Installation is very easy from just one side of the duct. Two different penetration depths are available, enabling the measuring device to be adapted to highly diverse duct diameters.
