Features

• You can measure roughness by comparing a standard plate to the actual product.
• You have two options: using sight or touch.
• For most surfaces, the touch method works well.
• The JIS standards agree, especially when you measure the highest peaks and valleys.For a more sensitive touch, use your fingernail instead of your fingertip.
• Or, you could use a pencil’s tip for a gentle scrape.
• But, if you’re checking surface shine, you must look at the surface.
• Usually, you can spot or feel roughness levels up to about 0.8S.
