As an upgraded version of pH meter pro V1, the secondary generation pH meter pro greatly improves the precision and user experience. The onboard voltage regulator chip supports the wide voltage supply of 3.3~5.5V, which is compatible with 5V and 3.3V main control boards, such as Arduino and LattePanda. The output signal filtered by hardware has low jitter. The software library adopts the two-point calibration method, and can automatically identify two standard buffer solutions (4.0 and 7.0), so simple and convenient. It uses an industry electrode and has a built-in simple, convenient, practical connection and long life, very suitable for online monitoring.

 

This industry pH combination electrode is made of a sensitive glass membrane with low impedance. It can be used in a variety of PH measurements with fast response, and good thermal stability. It has good reproducibility, difficult to hydrolysis, and basically eliminates the alkali error. Between 0 to 14 pH range, the output voltage of the electrode is linear. The reference system which consists of the Ag/AgCl gel electrolyte salt bridge has a stable half-cell potential and excellent anti-pollution performance. The ring PTFE membrane is not easy to be clogged, so the electrode is suitable for long-term online detection.

With this product, the main control board (such as Arduino), and the software library, you can quickly build the pH meter, plug, and play, no welding. DFRobot provides a variety of water quality sensor products, uniform size, and interface, not only meeting the needs of various water quality testing but are also suitable for the DIY of multi-parameter water quality tester.

The pH is a value that measures the acidity or alkalinity of the solution. It is also called the hydrogen ion concentration index. The pH is a scale of hydrogen ion activity in the solution. The pH has a wide range of uses in medicine, chemistry, and agriculture. Usually, the pH is a number between 0 to 14. Under the thermodynamic standard conditions, pH=7, which means the solution is neutral; pH<7, which means the solution is acidic; pH>7, which means the solution is alkaline.
