1、 Product overview

First of all, thank you for choosing our products and browsing the technical manual.

The Rockwell hardness test adopts the method of measuring the indentation depth, and the hardness value is directly read out through the indication, so the operation is simple and convenient, easy to master, and the work efficiency is high, which is suitable for the inspection of bulk parts and components; Rockwell hardness test method can use diamond indenter and rigid ball indenter, and can measure hard and soft samples. It is widely used. Therefore, Rockwell hardness tester test is widely used in production and has become the main test method to inspect product quality and determine reasonable processing technology. Rockwell hardness tester is the most commonly used test instrument for hardness test, teaching and scientific research in production enterprises, universities and scientific research institutions.
