Starting with the grounding of the family company on 01.11.1911, Messko developed rapidly during the first few decades of its existence to become one of the leading suppliers of the automotive industry. Radiator thermometers and air pressure gauges were the initial basis for the company's success.
In 1932, using the principle of the Bourdon spring invented by Frenchman Bourdon, Messko developed the second and most important basis for today's success: the first remote thermometer for the automotive industry and in 1960 the first thermometer for transformer manufacturing.
Today as a member of the MR Group Messko enjoys a leading position in the segment of temperature and oil level indicators for power transformers.
