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
