History of the firm:
In 1911 the production of electrical measuring instruments commenced in a small workshop in the town of Blansko near Brno. It was the first production facility of this type in the former Austro-Hungarian Empire and one of the first such manufacturers in Europe. Those were the times of significant technical and industrial development and steam machines and the first electric machines could no longer do without electrical measurement. At the beginnings of the manufacture of electrical measuring instruments was an outstanding Czech inventor, Ing. Erich Roucka. His workshop was soon to expand into a small factory. Employees, being guided by Ing. Roucka, quickly learnt new techniques and the factory’s products soon acquired an excellent reputation on the market." Source: http://www.metra.cz/en/about-us/
