DR-7 Direct Reading Ferrograph

The DR-7 Direct Reading Ferrograph quantitatively measures the concentration of wear particles in oil, while also providing basic wear trend data to help determine equipment condition within minutes.

Feature

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.

Feature

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.

Additional Features

Flexible
No limitations in lubricant type being monitored
Saves Time
Data can be obtained quickly, typically less than a few minutes
Reliable
Microprocessor incorporates internal diagnostics for reliable functioning

Want to Focus on Wear Particles?

Used in the analysis of in-service oil, the Direct Reading Ferrograph is a trending instrument – providing readings that measure the number of metallic particles, both large (DL) and small (DS) in an oil sample.

Identifying Wear Particles

In a previous blog we discussed Wear Particle Counts (WPC) derived from the Dl and Ds numbers calculated by a Direct Reading Ferrograph (DR).

Going Beyond Oil Analysis

There’s no better tool than oil analysis for predicting and preventing problems and optimizing machine performance. However, to understand what is really happening, you should consider multiple inputs involving your processes, practices, personnel, and application of the lubricant.
