A pH meter is an instrument used to determine the pH value of a solution. pH meter is a common analytical instrument widely used in agriculture, environmental protection and industry. Soil pH is one of the important basic properties of soil. Factors such as the temperature of the solution to be tested and the ionic strength should be considered during the pH measurement.
