Thanks to its flat, minimalist design and simple operating concept, it offers maximum flexibility. Its automatic electrode recognition, high accuracy and numerous diagnostic functions are particularly impressive for robust measuring tasks. Anyone looking for comparable functionality should take a look at the [Hanna Instruments HI2211 pH Bench Meter], which also ensures reliable pH measurements in laboratory environments.
Performance features and ease of use
The Edge device enables standardized pH measurements in the range from -2,000 to 16,000, whereby the resolution and accuracy can be adjusted depending on the mode. Particularly noteworthy is the automatic calibration of the glass electrode used. The technology automatically registers the serial number and calibration data of the smart electrode. The following points illustrate the key features:
- pH measuring range from -2.000 to 16.000 for reliable results in various applications
- Automatic electrode recognition via 3.5 mm jack plug
- Up to three-point calibration in simplified mode and up to five-point calibration in standard mode
- Precise temperature compensation (from -5 to 100 °C) for maximum measurement accuracy
- Practical CAL CHECK™ system for detecting dirty or damaged electrodes
- USB and micro USB ports for uncomplicated data storage and PC connection
- Ergonomic and lightweight design with a weight of 250 g
The high level of flexibility is demonstrated by the fact that the system can be easily expanded to include redox potential measurement (ORP). All you need to do is connect the appropriate ORP electrode via the jack plug. The corresponding calibration data is automatically read out and transferred. The compact design and the option of using either a desktop docking station or a wall bracket round off the overall package.
Certifications and standards
Within laboratory analysis, devices like this are used in DIN and ISO-certified facilities, as they can work with high accuracy and traceability. The model is also an ideal choice for production facilities that require CE-compliant documentation due to its robust design and reliable measurement results.

FAQs
How often should the device be calibrated?
Calibration is recommended before every critical measurement process, especially if accurate figures are required for certification processes. In routine laboratory operation, daily calibration is usually sufficient.
Can I use any electrode cleaning solution?
The use of suitable, manufacturer-specific cleaning solutions is recommended. Standardized cleaning liquids ensure that no residues form and that the sensor membrane remains intact.
Do I need additional accessories for the ORP measurement?
An ORP electrode, which is available separately, is required for redox mode. This is simply plugged into the jack connection and automatically recognized.
Is the device suitable for mobile use?
Yes, thanks to its low weight and flat design, it is easy to transport. In combination with battery or mains operation, it can be used both stationary and mobile.
What to do if there are deviations in the measurement results
First check the calibration and cleanliness of the electrode. In the event of heavy soiling or damage, it is advisable to replace the electrode in good time in order to achieve consistently precise measured values.
Conclusion
This measuring device impresses with its precise measurement results, ease of use and versatility. Whether in the laboratory, in the food industry or in an outdoor environment: with its customizable measurement and calibration modes and modern, space-saving design, it meets a wide range of professional requirements.
