德國OTT      
　德國OTT公司成立于1873年,從事水文儀器研發、生產和系統集成的著名公司
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.

In more than 130 years OTT has become Europa's largest manufacturer of complete hydrometric systems. Today our subsidiaries and representatives in more than 90 countries throughout the world supply efficient solutions in the fields of hydrometry, meteorology and environmental technology. Modern technology and high product quality are the main pillars of our product philosophy - at the time of the company foundation and today. This fundamental philosophy is reflected in our company structure (25% from the company staff are highly qualified employees in R & D department).The quality standard is confirmed by ISO 9001 Certification and controlled on a daily basis by internal quality control systems.

Since 2002 our company belongs to the Danaher Corporation. In the field of water / water quality, OTT and Hydrolab form together the division of 'Hach Environmental', under the guidance of Hach Company. This division covers the needs of water quantity and quality measurement in natural waters and channels. We offer customised solutions according to the interests of our customers, from the single sensor to the country-wide measuring network for hydrometrical or meteorological applications.
