S·O·S Fluid Analysis

About the S·O·S Program

The S·O·S fluid analysis program monitors equipment health to prevent downtime and maximize lifetime. The program uses Caterpillar®-verified, ASTM laboratory methods. These methods are designed to identify wear and contamination in fluid samples. Certified analysts evaluate the sample results and offer a recommendation. The recommendation comes with an alert level of ‘No Action Required,’ ‘Monitor,’ or ‘Action Required.’

  • The S·O·S program offers oil, coolant, and diesel fuel analysis.
  • Our sampling services are available for Cat and non-Cat equipment.
  • We monitor equipment from many industries including construction, transportation, mining, power generation, marine, and more. 

Sampling Benefits

Fluid sampling is a non-intrusive and personalized preventative maintenance method. Monitoring equipment performance allows our analysts to offer recommendations that are unique to your equipment’s needs by carefully monitoring equipment performance. Identifying early signs of wear or contamination gives you the opportunity to intervene promptly. Early intervention may prevent equipment downtime and extend component life.

Laboratory Tests

Our lab applies ASTM methods with industry-leading instrumentation to provide you accurate and applicable sample results.
