Определение
pH
¦ noun Chemistry a figure expressing acidity or alkalinity on a logarithmic scale on which 7 is neutral, lower values are more acid, and higher values more alkaline.
Origin
early 20th cent.: from p representing Ger. Potenz 'power' + H, the symbol for hydrogen (the pH being derived from the reciprocal of the hydrogen-ion concentration).

PH meter
A 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". The difference in electrical potential relates to the acidity or pH of the solution. Testing of pH via pH meters (pH-metry) is used in many applications ranging from laboratory experimentation to quality control.
