Product Description

Manual Operation Rockwell Hardness Tester with Dial Display

Features:

1. The dial will display hardness value directly, indicator responses sensitively, show the hardness value accurately, the test value is more accurate than national standard;

2. One-time casted molding shell, stable structure and it is not easy to be out of shape. It can work under harsh environment; the shell coating adopted car paint technology with white color. it has strong scratch resistance capability and still look bright as new after use many years

Working principle of Rockwell hardness test:
The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, where A is the scale letter.
