HFRR Analysis Software
A standard test method for evaluating lubricity of diesel fuels uses a high-frequency reciprocating rig (HFRR)
[ASTM D6079, IP 450, ISO 12156-1]
Part of this method is to measure the wear area on a test steel ball.
The HFRR Analysis Software is a powerful and easy to use tool to acquire and analyse microscope images of those test steel balls.
