New touch screen Rockwell hardness testing machines 24 August 2023

ZwickRoell Indentec has introduced a new touch screen Rockwell hardness testing machine, which is available in two variants, the ZHR4150 and ZHR8150, to accommodate either classic Rockwell or combined Rockwell, and Superficial Rockwell, hardness testing respectively.

Zwick explains that these recently launched products build on the long-lasting quality and success of the previous ZHR series and feature innovative touch screen displays to make Rockwell hardness testing even easier and more consistent. “Like all ZwickRoell Rockwell hardness testers, these instruments support fast, accurate and efficient hardness testing across an extensive range of applications and industries,” highlights the company. 

The touchscreen interface has been designed with simple user experience as its guiding principle. Simplifying test set-up parameters, testing procedure, and results handling, all ensure the latest machines are the most efficient and simple to use Rockwell testers available. Incorporating testXpert software, ZwickRoell users will already be familiar with the format and layout, whilst a multi-language option ensures that users can work in a convenient language, selected at the push of a button.

The ZHR interface is available in two variants, the basic interface on the ZHR4150 and advanced interface on the ZHR8150, both utilising 7 inch full colour resistive touchscreens.

The basic interface offers a simple, easy to use and read display, stores the previous 20 test results, features automatic scale indication, multi-language support and the ability to output data to testXpert software, USB stick or computer.  The more advanced interface accommodates data statistics and averaging, in and out of tolerance evaluation limits, automatic scale conversions and curvature corrections, histogram display, sample standard deviation display and calculation limits. Both machine interfaces benefit from having the ability to integrate firmware updates through in-situ by ZwickRoell service engineers, enabling the latest firmware to be utilised throughout the lifetime of the machines.

All machine variants are supplied with a UKAS calibration certificate with technical support readily available from the company and cost-effective routine maintenance, and ongoing calibration, can be provided by factory trained engineers.
