A pH meter is an electronic device used to measure the acidity or alkalinity of a solution. The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 indicate acidic solutions, while values above 7 indicate alkaline (basic) solutions. Key components of a pH meter include: 1. **Glass Electrode**: This is the primary sensing element that measures the hydrogen ion concentration in the solution.
