The SG68, SG78 and SG98 SevenGo Duo pro™ instruments are easy to use, offer the highest possible accuracy and provide great functions and security features not found in other portable instruments. In addition to the many security features the SevenGo Duo pro™ instruments also have ISM®. This ensures that the correct and most up-to-date calibration of the connected sensor is always used for the measurement.
Intuitive Menu-Guidance in 10 Languages: Operation is extremely user-friendly thanks to flexible softkeys and large back-lit display. In addition, the instruments relay full sentences in 10 languages.
Intelligent Sensor Management (ISM®): ISM® leaves nothing to chance! Calibration data and history are stored in the sensor and transferred automatically upon connection to the meter.
Everything Included – Time Saver!: The field kit contains a meter, two ISM®-sensors, a rubber holster, a transporting case, sample bottles and buffer/standards. Works immediately!
