A pH electrode, also known as a pH probe or pH sensor, is the part of a pH meter that comes into contact with the substance being measured and is used to measure the electrode potential.

A set of industrial onlineThe pH measurement system usually consists of four parts: pH sensor, pH electrode, pH transmitter, electrode sheath, and cable.

GermanywtwWhat should I do if the electrode ball of the pH meter is broken?

The main reason for the breakage of glass bubbles in electrodes is due to external forces such as collision and compression. The pressure bearing capacity of electrode bubbles is generally≤0.6MPa， It is common to stir the electrode as a stirring rod during measurement, and to be careful during cleaning, drying, capping, and other processes to avoid excessive force and breakage. After it breaks, this electrode is probably unusable and needs to be re selected.

How should electrodes be protected during normal times?

The electrode should be stored inIn a dry environment ranging from 10 ℃ to 30 ℃.

At temperatures below-At 5 ℃, due to the freezing of buffer and electrolyte, the electrode may rupture.

Due to transportation reasons, when using electrodes, it is necessary to observe whether the sensitive membrane bubble is filled with solution. If there are bubbles in the membrane bubble, gently shake it downwards a few timesFill the membrane bubble with solution (like a thermometer).

ifIf the pH electrode is stored under dry conditions, it must be soaked for 24 hours before use, otherwise it is difficult to calibrate.

When the electrode cap is not used, the electrode should be placed in buffer solution and not in distilled water.

Each electrode needs to be calibrated in order to be compatible withWhen used in conjunction with a pH meter, a two-point calibration of the pH electrode should be performed using standard buffer solutions (pH 6.86, pH 4.00, or pH 9.18).

The frequency of measuring electrodes for accuracy or inspection depends on different application conditions(The degree of dirtiness in the application, deposition of chemical substances, etc.).
