Droplet Digital ph Meter With pH Range 0-14 pH is a device used to measure the acidity or alkalinity of a solution by determining its pH value. pH is a measure of the concentration of hydrogen ions in a solution and is expressed on a scale from 0 to 14, where pH 7 is considered neutral, pH values below 7 are acidic, and pH values above 7 are alkaline. A typical pH meter consists of a probe, a reference electrode, and a pH-sensitive glass electrode. The glass electrode is sensitive to changes in hydrogen ion concentration and generates a voltage signal proportional to the pH of the solution.
