OIL Analysis Level II
this advanced program dives deep into the science of lubricant degradation, wear particle analysis, and advanced diagnostic techniques to uncover hidden equipment issues before they escalate into failures. The course covers advanced topics including ferrography analysis, additive depletion trends, moisture contamination effects, and the integration of oil analysis with vibration and thermography data for comprehensive machine health assessment.
