Laboratory analysis is based on the periodic collection of oil samples to evaluate parameters such as contamination, viscosity, oil degradation, and the presence of wear metals. This method provides highly detailed information, but it represents only a snapshot of the system’s condition at a specific point in time.

Online monitoring, on the other hand, uses sensors permanently installed on the machine to continuously measure parameters related to lubricant condition and component wear. This enables real-time anomaly detection, early warning alerts, and corrective action before an issue develops into a failure.

Therefore, while laboratory analysis provides diagnostic depth, online monitoring delivers continuous visibility. Combining both technologies allows organizations to optimize maintenance strategies, reduce operating costs, and increase the reliability of critical assets.
