As successors to the inventors of the Vickers hardness test, UK Calibrations are probably the best company in the world to specify and supply Vickers hardness machines, and as authorised agents of Wolpert Wilson, can supply a full range of modern and accurate Vickers hardness testing equipment.

Wolpert Wilson Vickers / Knoop hardness testers are widely used for determining the hardness of small precision parts, thin material or wire, coatings, and performing case depth determinations (CHD, EHT, NHT) UK Calibrations also offer software-based measurement packages designed to increase productivity, accuracy and efficiency through automating the measurement and/or the stage navigation process.

UK Calibrations also supply a range of Universal hardness testers with Vickers function.

The 400 Series Knoop / Vickers Hardness Testers are versatile, user-friendly hardness testers for quality assurance or metallurgical research.

Providing an affordable and reliable solution for accurate Vickers and Knoop hardness scale testing, the tester features an automatic turret and crisp optics that have a total magnification of 100x and 400x. The system features eight dial selectable test forces ranging from 10 gf- 2 kg (see specifications). For easy sample mounting, models are equipped with a 100 x 100 mm precision XY-Stage with 25 mm movement in each direction.

The Tukon 2500 Knoop / Vickers automated hardness testers offer unparalleled performance, accuracy and efficiency compared to any other micro / macro hardness tester on the market today.

This instrument is offered in a number of different configurations ranging from entry level packages for the casual user, to advanced fully automatic automation systems for evaluating high volumes of samples. Together, an industry leading load range of 10 gf to 50 kgf and an innovative digital zooming capability for dramatically enhancing the magnification range of the optical path support a wide breadth of applications. All system control is handled through the Wilson Hardness Group's Minuteman automation software, where test method setups, data collection, case hardness depth graphing, statistical calculations, data export and much more functionality is provided for rapid testing and analysis.

The Tukon 1102 and 1202 Knoop / Vickers Series Hardness Testers offer a versatile and user friendly solution for a wide range of micro-hardness scale testing.

For single scale micro-hardness testing, the Tukon 1102 Tester is equipped with a three position turret which includes one indenter position as well as a 10x and 50x objective. For more demanding applications, the Tukon 1202 Tester is equipped with a six position turret, including two indenter positions as well as a 5x, 10x and 50x long working distance objectives. Both units include USB output, eight dial selectable test forces and an innovative touch panel user interface for rapid test method handling and data collection.

The Tukon 1002-series is available in two different models. Below table shows the technical specificatiions of both models and the differences between them.
