When we think about oil analysis, it really begins with the tools and modifications that are necessary to properly take an accurate oil sample. The key to accurate oil sampling is minimizing data disturbance by preventing contamination of the sampling equipment. When outside contaminants are introduced in any way, the analysis will come back with inconsistent reports. Oil analysis, at its core, tracks and predicts failure modes by trending data over time. Let's explore the equipment that needs to be installed to ensure contaminant-free sampling and the oil sampling methods that each of these tools requires.

Minimess Sampling Valves

Often called a sample probe, the minimess valve is one of the most common and consistently accurate modifications for oil sampling. These valves should be installed on an elbow for lines with a high viscosity. Minimess valves can also be used on low-pressure systems; however, low-pressure systems require a soft valve seat to avoid leakage.
