Direct Reading Ferrography

A powerful trendsetter in predicting equipment failure before it happens.

Measures metallic particles, both large and small
Tracks trends over time for predictive maintenance
Provides warning before catastrophic failure occurs

Why do you need Direct Reading Ferrography?

Direct Reading Ferrography tracks metallic particles in oil for predictive maintenance.

Trending Analysis

The power of direct reading ferrography testing lies in the trend you create over time. By taking consistent samples of equipment oil, you can detect spikes in wear particle concentration and plan for preventive maintenance before catastrophic failure occurs.


Direct reading ferrography focuses on two types of particles - large (DL) and small (DS). DL measures particles larger than 5 microns, while DS measures particles smaller than 5 microns in size.
