Send in samples of your gear box oil or hydraulic oil and get back a full report on the condition of both your lubricant and equipment. The report includes results for wear metals (including ferrography), additive concentrations, particulate and water contamination, and viscosity. Sample results will be emailed to you within three to five business days. If the lab discovers critical conditions, they will call you to provide guidance on how to address the problem. Kit includes six bottles with labels, so you can test multiple samples.
