EHD (Ultra Thin Film Measurement System)
The EHD2 Ultra Thin Film Measurement System is the latest evolution of the successful EHD instrument. It is now a fully automated computer controlled instrument for measuring the film thickness and traction coefficient (friction coefficient) of lubricants in the elastohydrodynamic (EHD) lubricating regime.
