Qdoser Go (Topas M) Automatic Dosing System

The Qdoser Go (Topas M) provides an automatic dosing solution for all manual grinders & polishers. A weighted dosing arm can be placed anywhere around the polishing bowl to control where the suspension hits the grinding/polishing media. Four 500 ml glass bottles can be filled through a separate lid, even during operation, and are quickly removed for easy cleaning. A backflushing function keeps the hoses clean. When used in combination with the Qpol M (Saphir M) series grinder/polishers the Qdoser start/stop is controlled by the grinder/polisher (all other settings are programmed on the Qdoser directly).

    As a stand-alone unit, the Qdoser Go (Topas M) allows you to add automatic dosing at any point in the future to a manual or automatic grinder/polisher. All dosing parameters are controlled directly on the Qdoser Go. When used in combination with the Qpol (Saphir) M series, it can be connected to the grinder/polisher to control the dosing start/stop automatically.
