The Water pH Meter is an essential tool for gauging the acidity or alkalinity of a solution. Operating on the principle of ion - selective electrodes, it measures the concentration of hydrogen ions in a sample. When the pH electrode is immersed in the solution, a potential difference is generated based on the hydrogen ion activity, which is then converted into a pH value. This water pH tester is widely used in various fields. In environmental science, it helps assess the quality of water bodies, as pH levels can indicate pollution or natural changes. In the food and beverage industry, it ensures product consistency, like in winemaking where the pH affects fermentation and flavor. The pH Meter offers high accuracy, often with readings precise to within ±0.01 pH units. It comes with user - friendly interfaces, making it accessible for both professionals and hobbyists. With automatic temperature compensation, it provides reliable results across different temperature conditions.​
