Universal hardness testers are hybrid instruments designed to perform various testing methods, including Rockwell, Vickers, Brinell, and Knoop, using a single machine. These testers follow the standard procedures defined by ISO, ASTM, and JIS, applying each method directly rather than converting between scales.
While most hardness testers are built to operate within a single scale, universal testers offer a wide range of test loads and can switch between methods without requiring physical setup changes. This makes them ideal for users who need to test different parts or materials using different methods, saving time, space, and operational costs.
Older generations of universal hardness testers had clunky mechanical structures composed of several parts and complicated weight stacks. Today, modern models equipped with load cell technology and closed-loop force feedback systems have significantly simplified operation and improved accuracy.
With a universal tester, a single platform can cover all major scales. Although the upfront universal hardness testing machine price is typically higher than single-scale machines, the long-term savings in calibration, maintenance, and after-sales support make it a smart choice for environments requiring fast, error-proof results.
Closed-loop universal testers, in particular, provide broader and more precise load ranges compared to traditional deadweight systems. This makes them suitable for both microhardness and heavy-duty applications. The NEMESIS 9100 series, in particular, is a standout model in its category. It offers a seamless load range from 200 gf to 3000 kgf in one integrated tester.
INNOVATEST is the trusted source of universal hardness testers tailored to various industries and budgets. This type of tester is available across a range of models, from digital universal hardness testers to easy-to-use, high-performance units and state-of-the-art systems built for advanced testing environments.
INNOVATEST offers various universal 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 universal testing. Up to 9-position rotating turrets allow for Rockwell, Brinell and Vickers testing all on one instrument, thus eliminating the need to purchase separate hardness testers for each hardness method.
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.
