Application
The high frequency reciprocating friction and wear tester can evaluate the lubricity of diesel oil (including diesel oil containing lubricants) under the condition of high frequency reciprocation. It can also be used to test the lubricating performance of lubricating oil and grease, and to measure the thickness of the oil film.
