        The roughness meter platform is one of the main accessories of the portable roughness measuring instrument. It is suitable for various domestic hand-held roughness meters. It provides a high-precision measuring platform and a column lifting system for it. The instrument can be adjusted easily, and its effect will be greatly improved. Reduce the operating difficulty of the instrument, especially when measuring high-precision parts, the effect will be more obvious. This product is also suitable for users who use roughness measuring instruments from other manufacturers (including foreign manufacturers), but a special connection part needs to be customized. Of course, special users for other purposes are not excluded.
