SOS analysis helps you by identifying and measuring various contaminants and sources of oil breakdown, thus helps prevent excessive wear and eventual failure of your machine.

With SOS, you can:

  • Detect problems early so they can be repaired before they become major failures.​
  • Monitor positives and negatives, so you won’t pay for repairing of components that are not broken.
  • Schedule downtime that fits into your workload.
  • Monitor maintenance schedules and manage your budget better.
  • Develop complete profile and history of each piece of equipment, keeping your equipment with high resale value.
