Rudolph Tietzsch was founded in 1950 in Castrop-Rauxel, Germany and initially specialised in precision mechanics and apparatus construction. The company built flow meters for use with gases, either as single instruments or in small series.
In 1953 Tietzsch developed a safety voltage tester with a precision display, this was designed with a new type of dust-proof rubber casing and was known as the Spannungs- Prufball (Voltage Test Ball). It 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 Tietzschs decision to expand production to include other test and measuring equipment for use in electrical engineering. Since 1980 this has led to the development of new products which incorporate digital technology. The Tietzsch Variosafe multimeter became standard equipment for mining electricians working underground.
Today Tietzsch develops and manufactures the following product ranges at its factory in Ennepetal ; VDE certified voltage testers including the Multisafe DSP4 , high voltage testers up to 36000 V, telescopic voltage testers for overhead lines, intrinsically safe measuring equipment, like the Omega Megasafe, for mining and chemistry applications and resistance measuring equipment.
Tietzsch use modern electronic techniques, high quality materials with specially designed casings to ensure their products fulfil the highest demands with first class quality and safety.
