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. For special sensors, this set of accessories must be used to make complex and precise adjustments."}
