OTT MESSTECHNIK - History
The history of our company is a history of novelties. In 1873, Albert OTT founded his 'Mathematical-Mechanical Institute A.OTT'. His first measuring instrument, a Current Meter from the year 1875, already set a standard. In the following more than 130 years, OTT has become Europa's largest manufacturer of complete hydrometric systems. The 'classical' OTT instruments like Current Meters or Water Level Recorders are still being world-wide references because of their outstanding quality and precision. The OTT Universal Current Meter C31 is known by hydrologists in the whole world as the measuring instrument for flow measurement. Since the begining of the sixties we have made ourselves a name and were established as market leaders for innovative and user-friendly solutions in the field of electronical water level monitoring, data collection and transmission.
