Enhance Testing with Rockwell Hardness Testers
Reliable Performance

Rockwell Hardness Tester - MODEL NO. RHT-LC1500-1A

With innovative design and functionality that enables a wide variety of measurements, the HR-600 Series delivers hardness testing that defies conventional thinking.

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

Model No. RHT-LC1500-1A

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.

High-End CNC Rockwell Hardness Testing Machine, providing a fully automatic Rockwell hardness test sequence

The HR-600 Series combines the functionality of several previous models:

Rockwell hardness testing, Brinell hardness testing, Brinell and Vickers depth measurement hardness testing and hardness testing of plastic materials. Supporting all test types in a single machine, this new series expands the range of available measurements.
With its high-resolution scale load cell developed uniquely by Mitutoyo that allows for high-precision test load feedback control and state-of-the-art design that delivers both aesthetics and usability on the ground, the new HR-600 Series enables hardness testing that defies conventional thinking.

New design with functional beauty With a table for mounting workpieces and head with vertical mobility, the HR-600 Series is built for operability and usability. Its new design is highly focused on end-user usability, and the entire product structure has been inventively modified for functional beauty — a true embodiment of Mitutoyo’s pioneering spirit.
