Roughness measurements can be useful to quickly identify locations where differences of wet slip resistance may exist. It can also be used to measure directional differences that might also create a slip hazard.
The TR210 Surface Roughness Meter can identify changes in surfaces due to wear over time and soiling caused by traffic.
Roughness measurement should be included as part of the ISO10545-17 test for Coefficient of Friction and an integral part of any in-situ measurements

The TR210 is our advanced model surface roughness tester, which features menu operation, automatic cut-off setting, 12 different selectable roughness parameters and both digital and graphical displays on a large LCD.
