A steel dust meter for grease or oil is an excellent choice to check the wear condition of bearings in ultra-low to high-speed rotating devices. This is a quick and effective measurement of steel dust particles in grease and oils to determine the status of the wear condition before vibration increases. The result is shown instantly and the portable instrument is very easy to use.

The method can be used for all rotating bearings where one can take samples of grease or oil. Among the applications include:
- Pumps
- Motors
- Robots
- Mills
- Paper manufacturing
- Fans
- Rollers
- Conveyors
- Roller staircases
- Elevators
