INNOVATEST Rockwell hardness testers are designed for both standard and superficial Rockwell testing methods. These testers follow the procedures outlined in ISO 6508, ASTM E18, JIS Z2245, the most widely used standards for measuring material hardness globally.
Manual, semi-automatic and fully automatic Rockwell hardness tester methods are applied to a broad range of metals and plastics. The method works by measuring the depth of a permanent indentation created by a defined indenter under a specific (pre) load.
Depending on the material and application, different Rockwell scales may be used, such as Rockwell HRC for harder steels, HRB for softer metals like brass, and superficial scales for thin materials or coatings.
With minimal sample preparation required, the Rockwell test remains one of the fastest and most user-friendly hardness testing methods used across diverse industries. The main advantages of using a hardness tester with the Rockwell method are:
First, a minor load (preload) is applied to establish a zero or reference point. Then, a major load is added to reach the full test force and is held for a set dwell time to account for elastic recovery in the material. Once the major load is removed, the minor load remains in place, and the depth difference from the original reference point is used to calculate the Rockwell hardness value.
INNOVATEST offers various dedicated Rockwell hardness testers that are closed loop, load cell-based machines. Our instruments are developed, designed and endurance tested at our R&D facilities, and offer our customers the choice between basic manual testing or fully automatic Rockwell testing
All instruments are equipped with user-friendly, advanced IMPRESSIONS software, which allows for ease of use while accommodating complex applications and workflows. In addition, all critical internal electronic components are manufactured by INNOVATEST, allowing for a high level of manufacturing quality control and ensuring a reliable hardness testing instrument for many years, backed by our extended warranty options.
Choosing the right hardness tester depends on your material type, load requirements, and testing environment.
