The SevenGo Duo pro™ meter features high measurement accuracy, user-friendly operation and exceptional safety.
SevenGo Duo pro™ meters are ideal for special testing, especially in environmental protection and the chemical and food industries.
The complete set of instruments is especially useful for off-site measurements, as both the meter and sensors are waterproof.
The innovative ISM sensor management system provides the user with an even higher level of security.
The calibration data are stored in an integrated circuit located in the sensor head. They are automatically transmitted to the meter just after the sensor is connected to it. This ensures that the meter uses up-to-date calibration data.
Reliable RDO technology uses OptiOx™ optical measurement system to determine dissolved oxygen so measuring dissolved oxygen is now easier.
