PTl InstrumentsWho is PTL Dr. Grabenhorst GmbH?

PTL is a continuation of an electrical workshop founded in 1947 in Bamberg by Master Engineer Georg Müller under the name PHYS.-TECHN. LABOR. They are a manufacturer of test equipment for safety and conformity to a specific standard.

In 1965, the company was transferred to Stadtsteinach and taken over in 1974 by Dr.-Ing. Dieter Grabenhorst. In 1984, the registered name changed to PTL Dr. Grabenhorst GmbH. In 1986 the buildings were acquired and enlarged, where PTL is accommodated today.

The following years stood out for their continuous expansion in the areas of quality assurance, product and production improvement as well as international partnerships.

Dr Grabenhorst retired end of 2005 and his son Juergen Grabenhorst took over the company. In September 2017, PTL celebrated their 70th anniversary.
