SurfaceVue 10 has been comprehensively tested by third parties and copies of those reports are
https://www.teconer.fi/en/surface-condition-friction-measurements/
.The tests
indicate that the accuracy of the SurfaceVue 10 friction reading measured as a standard deviation
of the difference to an absolute physical friction meter is on the order of 0.10. This accuracy is
adequate for winter maintenance purposes.
