The purpose of oil sampling is to achieve the highest level of machine performance and reliability at the lowest possible cost. Initial samples serve to establish benchmarks and to identify machines with critical contamination levels. Routine sampling serves to document that goals are met and can indicate abnormal wear that needs to be addressed.
The best sampling point is between the pump and the filter housing of an off-line filter, which is normally the most highly contaminated part of the oil system. If no off-line filter is installed, a vacuum sampling pump is a valid option. In such case, the sample should be drawn 10 cm above the lowest part of the tank.
To take an oil sample properly, we suggest using an oil sample kit from C.C.JENSEN A/S. This includes a 200 ml particle-free glass bottle in ready-to-send packaging.
C.C.JENSEN A/S performs oil analyses with independent laboratories and has extensive experience in properly interpreting analysis results.
