    Digital Age Entry

    In 1992 after the early death of Albert Gnehm jun. Mrs. Sylvia Scherer-Ospel becomes responsible for the management. Under her leadership, the digital hardness tester "SwissMax 300" is developed already in 1996. Further development in the field of equipment and ease of use leads ultimately to "SwissMax 600" and Gnehm’s own GMS software. Even today, this universal hardness tester is setting standards: An all-rounder with plenty of comfort and reliable precision - Quality Made in Switzerland!

    New impetus for the future!

    Mrs. Scherer-Ospel retires from GNEHM Härteprüfer AG, after 40 years. Mr. Roger Deuber becomes the new owner; Mrs. Felizitas Glunz takes over as managing director. For the coming decade, once again further optimizing of hardness tester and its software is in focus of business activities. A first step is the Swiss Pacer, already developed with the participation of Roger Deuber. More automated and modular hardness testers will follow - Quality made in Switzerland!
