1. In electronics, a sensitive voltage measuring device based on a null technique which provides infinite @I02988@ at null.
  2. In chemistry, potentiometric methods involve the measurement with a potentiometer of voltage generated in a cell. A high @I02988@ digital voltmeter is often used today as a convenient alternative to a potentiometer.
