100 years history | In the late 1920s, Mr. Albert Gnehm Sr. developed his first Rockwell hardness tester, initially for his personal use, marking the inception of what would become today’s GNEHM Härteprüfer AG. With a focus on innovation and precision, this pioneering effort laid a strong foundation for the company’s growth. Building on his father’s legacy, Albert Gnehm Jr. continuously improved and modernized the technology, propelling GNEHM hardness testers to a leading position worldwide — proudly delivering Swiss-quality excellence.
