The EHD-HS operates at up to 20m/s, measuring lubricant film thickness down to 1nm in the elastohydrodynamic lubricating regime. Without a doubt the EHD-HS represents the cutting edge of lubricant film testing

The ability of the EHD-HS to run at speeds up to 20m/s makes it a fantastic choice for researchers studying high speed applications such as electric vehicle drivetrains, and to study the effect of additives in automotive lubricants, metalworking fluids, emulsions, turbine oils and greases.

The EHD-HS is capable of running at speeds of up to 20m/s, ideal for high speed applications such as electric vehicle drivetrains, having the following features:-

• State of the art software and mechanical system that ensures reliability, repeatability and usability
• High sensitive camera for impressive image quality
• Precision components enable accurate measurements down to 1nm
• Two independently driven motors allow any slide / roll ratio to be achieved enabling many applications to be replicated
• Fully automated and easy to calibrate
• Requires a small volume, minimising wastage and cutting running costs
• Traction coefficients can be measured at any slide/roll ratio from pure rolling up to pure sliding.
