SevenGo Duo pro™ combines maximum measurement accuracy and an excellent range of functions with user-friendly operation and exceptional safety. SevenGo Duo pro™ meters are essential for special analyses, particularly in environmental, chemical and food & beverage industry. The kit versions are also well suited for outdoor use because both the meter and the sensors are watertight (IP67).
The revolutionary intelligent sensor management system (ISM^®) offers the user an even greater level of security. The calibration data is stored on the chip in the sensor and is used automatically when the sensor is connected to the meter. This ensures that the meter always uses the latest calibration data.

The OptiOx optical measuring system for determining dissolved oxygen is based on the reliable RDO^® technology. Thanks to RDO^® (Rugged Dissolved Oxygen), measuring dissolved oxygen is easier than ever before.
