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.
