RUDOLPH TIETZSCH was founded in 1950 in Castrop-Rauxel, initially specialising in precision mechanics and apparatus construction. In those days, the company built test equipment (e.g. flow testers for use with gases), either as single instruments or in small series, for industrial customers in the Ruhr area.
In 1953, the company developed an especially robust and safe voltage tester which possessed a precision display. Designed with a new type of dust-proof rubber casing, the Spannungs-Prüfball (Voltage Test Ball) achieved rapid recognition among heavy industry and energy suppliers as a result of its reliability and highly safe operation.
The success of the Voltage Test Ball led to the decision to expand production to include other test and measuring equipment for use in electrical engineering. This general development in the field of electronics has led since 1980 to the creation of new products which incorporate digital technology. The inherently safe multimeter, Variosafe, became a standard equipment item for mining electricians working underground.
By using modern electronic techniques, high quality materials and highly developed casing designs, Tietzsch products fulfil the highest of demands. Our customers have for decades enjoyed the first-class quality and safety that Tietzsch products give them.
