Avoid maintenance cost – detect wear and tear
Fast detection of iron in oil: SDM-73
In the grease of stressed joints you will find iron particles caused by abrasion. The amount of iron in the oil is a good indicator for the greasing quality. It tells you if the oil need to be changed.
Just take an oil sample with a disposable syringe and insert into the cuvette. The SDM 73 gives you a direct reading of the iron concentration. The iron content is displayed in ppm. Starting with a certain concentration an oil change is recommended.
Recommendations |
|||||||
|---|---|---|---|---|---|---|---|
| Concentration | Activity | ||||||
| < 30 ppm, big machines < 100 ppm | No activity | ||||||
| 30 – 100 ppm, big machines 100 – 300 ppm | Change oil check again after 1 month | ||||||
| > 100 ppm, big machines > 300 ppm | Improve system, measure more frequently | ||||||
