Metrawatt

On August 20th 1906 Metrawatt was registered as the company "Dr. Siegfried Guggenheimer". Forced by the Nazi, Dr Guggenheimer had to rename the companies name to a new name without the relationship to a Jewish owner. The Company was renamed to "Metrawatt AG, Fabrik electrischer Messgerate". Metrawatt started with construction of exposure meters in 1936 with Tempophot and in a later stage with the Horvex, Leicameter MC with selenium sensor and later in 1963 with the version MR with CdS sensor. In 1992 The company merged with Gossen into "Gossen-Metrawatt GmbH"
