DEVICE FOR MEASURING PH AT TEMPERATURE

摘要

The invention relates to a measuring device (1) for measuring the pH of a solution to be measured comprising: a reference cell (2) including: a tank (20) filled with an electrolyte solution; a platinized platinum reference electrode (21) immersed in the tank (20); a measuring cell (4) including: a platinized platinum measuring electrode (41) to be immersed in the solution being measured; wherein the measuring device (1) also comprises: a temperature regulator (RT) to ensure the same temperature in the reference cell (2) and the measuring cell (4); a partial pressure regulator (RPP) to ensure the same hydrogen partial pressure in the reference cell (2) and the measuring cell (4).
