Blansko and its surroundings are known worldwide as the metropolis of the production electronic devices and measuring technology, which was started here at the beginning of the 20th century by Mr. Ing. Erich Roučka, also known as the Moravian Edison. In 1911, he founded the first factory for electrical measuring instruments in Blansko in the historical territory Austria-Hungary, also the first in Central Europe. Due to the many years of tradition in our region, our goal is to further expand the development of electronic devices and their production in the Blansko region.
