Advanced Design

The DR-7 features an interactive 7″ LCD touch screen, and USB and Ethernet port so you can easily plug in a keyboard, mouse, access useful reports on the web, and connect it to our other Ferrography instruments like FM-6 Ferrogram Maker and the FS-6 Ferroscope.


Magnetic Gradient

The DR-7 Ferrograph uses a magnetic gradient to trap and optically measure the concentration of ferrous wear particles on a scheduled basis. The instrument also establishes the baseline wear level for any piece of equipment. Any sudden increase in the wear trend level alerts the user to potential problems prompting preventive actions.
