Let’s transport ourselves back to 1911, when Erich Roučka, a visionary engineer, came up with a revolutionary idea—he became the first in Austria-Hungary to manufacture electric measuring instruments and control systems for thermal technology. His factory quickly expanded, and its innovations earned admiration and respect.

During World War I, production surged, supplying key technologies for military purposes. However, after the war, a downturn followed. Roučka didn’t give up—he embarked on a study trip to America, where he absorbed new knowledge and returned with a bold vision. His factory began producing automatic boiler controls, electrical equipment for mines and steelworks, and much more. Throughout his lifetime, he patented an astounding 850 inventions!

In the 1930s, he built a modern factory in Slatina, but in 1934, he sold his Blansko factory to entrepreneur Robert Sochor. This factory then became Sochor’s Factory, thriving until its nationalization in 1945.

And it was there that this laboratory ohmmeter was born.
