A liquid pH sensor is a device used to measure the pH level of a liquid, indicating its acidity or alkalinity. These sensors are commonly used in various applications including water quality monitoring, chemical processing, and laboratory research. They provide real-time pH readings, which can be crucial for maintaining the desired chemical balance in a liquid.
