pH meter is often used in chemical analysis for the measurement of pH of water-based solutions. However, it is a type of potentiometer because it measures the potential difference between the pH electrode and a
while potentiometers are typically used for low-power applications where voltage division or signal control is required, and precision control is desired. However, the specific choice between a rheostat and a potentiometer will depend on the requirements of your particular circuit and the parameters...
