Principle and Introduction of pH Electrode

The principle of pH electrode measurement is electrochemical method and the principle of primary battery. primary cell

It is a system that converts chemical energy into electrical energy. This electricity

The voltage of a pool is called electromotive force (EMF). This electromotive force (EMF) is generated by

Composed of two and a half batteries. One of the half cells is called the measuring cell, and its

The potential is related to specific ion activity; The other half cell is the reference half cell

A pool, commonly referred to as a reference electrode, is typically connected to the measuring solution and

And it is connected to the measuring instrument. Electricity generated through the reaction of the primary battery inside the electrode

The potential difference is transmitted to the pH controller, and the corresponding algorithm sends the displayed pH value.

Precautions for using pH 2 electrodes

Precautions for using pH 2 electrodes

(1) The electrode leads are special shielded wires, and customers are prohibited from splicing leads without authorization

We are not responsible for any consequences caused by the line.

(2) Long term immersion in distilled water or protein solutions should be avoided, and

Prevent contact with organic silicone grease.

(3) The glass film of electrodes that have been used for a long time may become transparent

If there is sediment attached, it can be washed with a dilute solution and rinsed with water.

(4) When you perform maintenance and upkeep on the electrodes, you still cannot calibrate them

The program and normal testing indicate that the electrode is no longer able to recover its response. Please replace the battery

Extreme.

(5) The pH electrode wire is not waterproof and should be avoided from coming into contact with water as much as possible.

(6) The shelf life of the electrode is one year, and it should be used as soon as possible after purchase,

Not suitable for storage for too long.
