Features:
1: The roughness vertical comparator comes standard with 6 samples of different roughness levels, providing you with a wide range of choices, easily distinguishing and comparing different qualities, that the product meets the highest standards: 2: It can measure the roughness of six processing for methods (horizontal milling, vertical milling, turning, flat grinding, grinding, cylindrical grinding), and can perform various functions such as measuring different types of and detecting various textures.
3: These standard kits are made of 45 super carbon steel, which is strong, not easy to deform, Advanced technology, stable quality, complete grade specifications, high hardness, good wear resistance. It has a protective oil film, you can rest assured to use it repeatedly for a long time to for ensure accuracy and reliability
4: The comparison and differentiation table is clear. The standard set model is clearly marked, and the samples are neatly arranged.
