18 Οκτ 2015 · The basic principle of the pH meter is to measure the concentration of hydrogen ions. Acids dissolve in water forming positively charged hydrogen ions (H+). The greater this concentration of hydrogen ions, the stronger the acid is.
17 Δεκ 2015 · A pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) of liquids and semi-solids. It consists of glass and reference electrodes connected to an electronic meter that measures and displays the pH reading.
5 Οκτ 2019 · This document discusses the measurement of pH. It begins by defining pH as the negative logarithm of the hydrogen ion concentration. It then discusses how pH meters work by measuring the voltage difference between a pH-sensitive glass electrode and a reference electrode.
