No matter whether monitoring of transmission, opacity, extinction or dust concentration is required, the FW300 Ex dust measuring device can take care of it. Each measured quantity can be freely selected. The FW300 Ex measures immediate and precise even during difficult conditions such as sticky dust loads, high gas temperatures or variation in gas velocities. Device types with flameproof or dustproof housings are available for applications in potentially explosive atmospheres.
