ROCKWELL HARDNESS TESTER 

MRT-AL 150

Why Rockwell Hardness Tester

The Rockwell is a hardness scale based on indentation hardness of a material. Rockwell Hardness Tester is suitable for testing hardness of metals and alloys. These testers are simple in design and easy to operate, still yet quite sensitive and accurate.

MRT AL-150: It's Automatic weight selection with automatic zero setting dial gauge with more testing height and throat.

We at Multitek Technologies perform wide range of Rockwell Hardness Testers test for the hardness value of various materials according to Rockwell Principles. The testing procedure is according to ISO 6508 and ASTM E18.

Tactics of Measuring Rockwell Hardness

The Rockwell hardness test measures the hardness of metallic materials in the simplest possible way, i.e. by pressing an indenter into the surface of the material with a specific load and then measuring how far the indenter has penetrated. Most of the time, the indenter is a steel ball or a diamond.

Benefits of performing Hardness Testing

The Rockwell hardness test is used for macro hardness tests, which are generally defined as tests that use indentation loads below or equal to one kilogram-force.
