Overview

The main measuring components of the Hash PRO-P3 online pH meter are a glass electrode and a reference electrode. The glass electrode is sensitive to pH, while the reference electrode is relatively stable. Placing the two electrodes of pH together in the same solution forms a primary cell, and the potential of this primary cell is the algebraic sum of the glass electrolysis and the reference electrode.

Hash PRO-P3 online pH meter

Working Principle:

Detection principle: The main measuring components of a pH meter are a glass electrode and a reference electrode. The glass electrode is sensitive to pH, while the reference electrode is relatively stable. Placing the two electrodes of pH together in the same solution forms a primary cell, and the potential of this primary cell is the algebraic sum of the glass electrolysis and the reference electrode. The reference electrode potential of a pH meter is stable, so under constant temperature, the potential change of the original battery composed of solution and battery is only related to the potential of the glass electrode, which depends on the pH of the solution to be measured. Therefore, by measuring the potential change, the pH value of the pH solution can be obtained.
