Ph meter standardization
WebbA pH meter is a scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH.The pH meter measures the difference in electrical potential between a pH electrode and a reference electrode, and so the pH meter is sometimes referred to as a "potentiometric pH meter". http://aashtoresource.org/university/newsletters/newsletters/2016/08/02/calibration-vs.-standardization
