Successful family business
A company with tradition.
Founded in 1946 as a craft business, Gräff GmbH is now a modern company delivering sustainably designed temperature measurement technology. Despite the development process in these almost 80 years, we look back on a family business based on partnership together with today’s Managing Partner Marion Hupperich. Partnership is paramount and filled with meaning, both among employees and towards customers.
