Rockwell Hardness Testing Machines from UK Calibrations

Rockwell Hardness Testing Machines

UK Calibrations are distributors for Wolpert Wilson Instruments hardness testers from the USA. Wilson Instruments introduced the first Rockwell tester to the market over 80 years ago. The simplicity and robustness of the test, invented by Stanley P. Rockwell, revolutionised hardness testing. It was fast, accurate and allowed the part to be used after testing.

The Wolpert Wilson Rockwell Series 500 and 600 provide proven reliability and precision at an affordable price for your standard Rockwell tests like HRC, HRB and HRA on any metal like steel, cast-steel, brass, bronze and aluminium.

Their latest product is the 2000-series. The fastest and most accurate closed loop Rockwell tester on the market. The Twin model is capable of testing both Regular Rockwell (HRA, HRB, HRC, etc.) and Superficial Rockwell (HR15N, HR30T, etc.).

We also supply a range of Universal hardness testers with Brinell function.

Rockwell 2000-R / 2000-S / 2000-T

The Rockwell 2000 series hardness tester uses a unique, closed-loop electronic control system and load cell mounted directly on the indenter to eliminate errors. This ensures that preliminary and total forces are applied with unparallelled accuracy and repeatability. The 2000 series uses optical linear measurement technology to achieve the highest level of depth measurement accuracy and resolution available. There are no mechanical linkages or sources of friction between this measuring device and the tested part. This is a major improvement over conventional dead-weight hardness testers.
