Ra (Roughness Average) meter is used to measure the microscopic average roughness (Ra) of a concrete surface. 

• Simple to use.
• Eliminates the need to go back steps to remove missed scratching.
• Confirms the correct surface has been achieved for each stage of polishing.
• Allows the polishing process to be completed more efficiently with conclusive standards achieved.
• Used in conjunction with our 5 step polishing process.
