Rockwell hardness tester is defined as the indentation resistance and determined by measuring the permanent depth of an indentation after undergoing a preliminary force. The more shallow the indentation, the harder the material. Rockwell testing is defined with the ASTM E18 industry standard for the testing procedure. The Rockwell hardness measurement is calculated by first applying a preliminary test force, called a preload, for a specific period of time, called dwell time. The preload penetrates through the surface of the material to eliminate any interference caused by the surface finish of the test specimen. This point reached represents the zero point, also known as the reference point.Read More...
The NG-RockGen Analogue Rockwell Hardness Tester is designed to test the hardness of metals by determining the depth of penetration of an indenter under a large load compared to the penetration made by a preload according to the Rockwell regular scales.
The NG RockGen Digital Series provides an automatic, digital, high accuracy solution to your Rockwell testing requirements. The Digital series is completely automated and is available in Rockwell Regular or Rockwell Superficial scale configurations.
