If particle counting is not possible directly on your system, you can use the LasPaC-II bottle sampling unit to extract oil samples for subsequent analysis. Fluids which contain a large amount of air cannot be measured correctly. To remedy this, the bottle sampling units are equipped with a vacuum pump which can remove air from the oil sample. STAUFF offers bottle sampling units for the LasPaC-II particle counter in two sizes: 110 ml and 500 ml.
