Original price was: $195.00.Current price is: $50.00.

Varnish and Deposit Identification and Measurement (VIM) Certification Preparation is an online certification course designed for lubrication, reliability, and maintenance professionals. Participants will learn how lubricant degradation and contamination contribute to varnish and deposit formation, how to select and interpret oil analysis tests to assess deposit risk, and how to develop and evaluate mitigation strategies that improve equipment reliability. The course is ideal for reliability engineers, maintenance managers, laboratory technicians, filtration specialists, and other professionals responsible for lubricant management and machinery condition monitoring.
