Oil condition monitoring (OCM) is a predictive maintenance technique used to assess the health and performance of machinery by analyzing lubricant properties. It helps detect contaminants, wear particles, and oil degradation in engines, turbines, hydraulic systems, and industrial equipment. By providing real-time insights, OCM enables industries such as automotive, aerospace, oil and gas, power generation, and manufacturing to optimize maintenance schedules, prevent unexpected failures, and extend equipment lifespan.
