Xtra easy: Fast and easy analysis of ferromagnetic particles
eratest ferro allows for the simple quantitative analysis of ferromagnetic particles in oil and grease samples. With the integrated ARM high-performance processor, the built-in rechargeable battery and the 5-inch touchscreen, measurements are completed within one second. An automatic and a manual measuring mode allow the user to customize the eratest ferro exactly to individual requirements.
The concentration of wear metals is determined with just 2 mL of sample. And all this without any sample preparation or special training of the operating personnel. The management of information about the sampled assets enables clear allocation of the results. The associated alarm values make it easy to immediately recognize any problem.

Frequently Asked Questions about eratest ferro
Yes, there is a definite correlation between the unitless PQ™ index and ferrous debris measured in ppm, provided the PQ™ Index values are not exceptionally high.
A study published by a third party, in which over a thousand samples were analyzed using both a standard PQ™ Index device and a typical ferrous debris monitor, reached the following conclusions:
Up to values of 2000 ppm a good correlation could be shown. A factor of approximately was determined; that is, a PQ™ index of 100 corresponds to approximately 200 ppm.
Looking at the broad set of data, results show a skew once the PQ Index exceeds 1000 (2000 ppm). This is likely due to the design of PQ monitors, which typically use a measurement coil below the sample and only analyze the bottom of the fluid. Consequently, they are highly sensitive to particles at the bottom of a sample but insensitive to those suspended at the top. For more details contact our service and support team >>
Yes, it is definitely possible to determine the ferromagnetic content of grease samples. The eratest ferro is specifically designed to function as a mobile analyzer for measuring the total content of ferromagnetic wear particles in greases, as well as in oils and coolants.
The device performs this quantitative analysis in just one second and operates in accordance with the ASTM D8120 standard. To accommodate grease analysis, the device comes supplied with specific accessories, including specialized grease vials, a scraper, and a grease sample holder. The user simply uses the scraper to place a representative grease sample into the notch of the sample holder, smooths it out, and inserts it into the vial for testing.
