SevenGo Duo Portable pH Meter
Advanced Handheld Meters to Measure pH, Conductivity, DO, and Ion in Any Workplace
The SevenGo Duo is a handheld pH meter to measure multiple parameters, including pH, conductivity, ion concentration, and dissolved oxygen. Applications like environmental monitoring and water and food quality analysis require high accuracy and mobility in their measurements. The SevenGo Duo comes with a large and clear display, data storage functionalities, and ease of operation, ensuring both precise and reliable measurements for these critical applications.
Advantages of Seven2Go Duo Portable Meters
Simple and Quick Operation
The high-contrast display, intuitive menu, and single-press buttons for calibrations and readings make these portable meters easy to use. With the attached electrode clip and ergonomic design, you can take the readings even with one hand.
Operating Modes
There are two operating modes – expert and routine. With the expert mode, you can configure functions to specific laboratory requirements and then switch to the routine mode for quick and easy execution of the configurated settings.
Waterproof and Robust
With the SevenGo Duo you do not need to worry about the measurement environment. The meter is IP67 certified, waterproof, and fully protected against dust particles; it is ideal for outdoor applications.
Reduced Chances of Errors
The fully integrated Intelligent Sensor Management technology offers advanced security. The meter automatically recognizes the sensor and stores the sensor ID, serial number, and last calibration data.
Compliance Support
The SevenGo Duo Pro provides extensive Good Laboratory Practice compliance support, making it an ideal pH meter for special requirements in regulated sectors or for measurement under extreme conditions.

Some of the key advantages include:
- It has five-point pH calibration with a choice of seven pre-defined and one user-defined buffer set.
- Data storage for 500 GLP data records with time/date, sensor ID, and SN, as well as user and sample IDs
- Intelligent Sensor Management (ISM®)
What are the seven reasons to choose the SevenGo Duo portable meter?
- Easy and intuitive operation
- High measurement accuracy
- Large, easy-to-read display screen
- Ergonomically designed, watertight, and robust
- Comprehensive range of practical accessories
- Modern GLP data management

What is the accuracy of SevenGo Duo and SevenGo Duo Pro portable meters?
The SevenGo Duo has an accuracy of ± 0.01 pH (±1 mV), and the SevenGo Duo Pro meters have an accuracy of ± 0.002 pH (± 0.2 mV). This is only the uncertainty of the meter itself. For the entire measurement chain, the best achievable accuracy is typically 0.02, but depends on many factors, such as the sensor state and sample properties.
What are the differences between the SevenGo Duo and the SevenGo Duo Pro?
- The SevenGo Duo model can store data up to 99 points, whereas the Pro version can store up to 500 points.
- Unlike the SevenGo Duo Pro, the SevenGo Duo does not have a backlit display.
- The SevenGo Duo does not have a multilanguage interface. The Pro version, however, has an interface in 10 different languages.
Which are the different types of portable meters available?
There are single-channel portable meters called Seven2Go Pro, and dual-channel portable meters called SevenGo Duo Pro in the Seven series portable meters. FiveGo portable meters are entry-level meters.
Seven2Go Pro meters can transfer data using EasyDirect™ pH software.
