Analog pH Meter Pro V2 Professional pH Sensor Compatible with Arduino and Raspberry Pi

DFRobot Gravity: Analog pH Sensor/Meter Kit V2 Introduction The new Arduino Analog pH sensor/Meter is compatible with Raspberry Pi and Arduino microcontroller. Attention： 1. The BNC connector and the signal conversion board must be kept dry and clean, otherwise, it will affect the input impedance, resulting in an inaccurate measurement. If it is damp, it needs to be dried. 2. The signal conversion board cannot be directly placed on a wet or semiconductor surface, otherwise, it will affect the input impedance, resulting in the inaccurate measurement. It is recommended to use the nylon pillar to fix the signal conversion board, allow a certain distance between the signal conversion board and the surface.

• DFRobot Gravity: Analog pH meter pro V2 is specifically designed to measure the pH of the solution and reflect the acidity or alkalinity. It is commonly used in various applications such as aquaponics, aquaculture, and environmental water testing.
• 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 board. 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.
• This industry pH combination electrode is made of sensitive glass membrane with low impedance. It can be used in a variety of PH measurements with fast response, good thermal stability. It has the good reproducibility, difficult to hydrolysis, and basically eliminate the alkali error. Between 0 to 14 pH range, the output voltage of the electrode is linear.
• The reference system which consist 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.
