On-Site Analysis, Inc. has revolutionized fluids testing. OSA’s high tech, table-top analyzers are powered by proprietary, predictive software and deliver diagnostic test results for oil, other lubricants, and coolants. No guessing or interpretation needed. Our reports spell out what specific actions are needed to remedy the problem identified. No lost samples, human errors, or waiting days to weeks for results. OSA started out as a fluids analysis laboratory, and has invested over $23 million to automate testing. We put the “lab in a box,” so service personnel can conveniently do condition-based maintenance in any service bay or in remote locations. Our customers have stopped sending samples out to labs, but are actually testing more using OSA anlayzers. Some have saved millions, while all have improved engine maintenance and helped the environment.
