Description
The DFRobot Gravity: Analog pH Meter Pro V2 is a specialized tool designed to measure the pH level of a solution and indicate its acidity or alkalinity. This device finds wide application in different fields like aquaponics, aquaculture, and environmental water testing.
The voltage regulator chip on board has a wide voltage supply range of 3.3~5.5V, making it compatible with 5V and 3.3V main control boards such as Arduino and LattePanda. The hardware-filtered output signal has low jitter, while the software library adopts a two-point calibration method that can automatically identify standard buffer solutions (4.0 and 7.0), making it simple and convenient to use. The industry pH combination electrode features a sensitive glass membrane with low impedance, enabling it to perform fast and precise PH measurements with good thermal stability and reproducibility. The Ag/AgCl gel electrolyte salt bridge reference system provides stable half-cell potential and excellent anti-pollution performance. The ring PTFE membrane is not easily clogged, making the electrode suitable for long-term online detection.
Using this product along with a main control board and software library, you can easily build a plug-and-play pH meter without any welding. DFRobot offers a range of water quality sensor products with uniform size and interface that can meet the needs of various water quality testing and DIY multi-parameter water quality testers. The pH measures the acidity or alkalinity of a solution and is expressed as a number between 0 to 14. A pH of 7 indicates a neutral solution, while a pH below 7 indicates an acidic solution and a pH above 7 indicates an alkaline solution. The pH has many applications in fields such as medicine, chemistry, and agriculture.
