Hardness Legacy Testers
Legacy Hardness Testers
Since 1936, Buehler has been at the forefront of materials preparation and hardness testing, building on a foundation of legacy machines trusted by industries worldwide. For over a century, Reicherter, Wolpert, and Wilson have pioneered groundbreaking hardness testers, setting the benchmark for quality and precision. Today, Buehler honors their legacy, continuing to innovate and meet the growing demands of modern manufacturing. For service inquiries, please contact our service team.
Wilson Hardness Legacy Testers
The Wilson® hardness brand of hardness testers was originally known as the Wilson Mechanical Instrument Company. Here Stanley Rockwell and founder Charles H. Wilson introduced the Rockwell hardness tester, an industry standard. Later, Wilson became the home of the legendary Tukon line of micro-indentation testers – renowned for Knoop and Vickers testing. These early inventions revolutionized industry and paved the way for Wilson today, with innovations that improve usability and allow for full connectivity and automation like the DiaMet software.
