GA151IpH glass electrode and SE23I reference electrode

GA151IpH glass electrode and SE23I reference electrode

STMGA151I and SE23IIt is a model of pH glass electrode and reference electrode, usually used for pH measurement. Here are their detailed information:

1. GA151I (pH glass electrode)

type：

PH glass electrode.

feature：

• Made of special glass film, sensitive to hydrogen ions (H ⁺) in solution.

• Used to measure the pH value of a solution.

• Usually has a wide measurement range and good response speed.

application：

• Laboratory pH measurement.

• Industrial process control (such as chemical, pharmaceutical, food processing).

• Environmental monitoring (such as water quality analysis).

maintenance：

• Rinse with deionized water after use.

• When not in use for a long time, the electrode should be soaked in a specialized storage solution to prevent the glass film from drying out.

2. SE23I (reference electrode)

type：

Reference electrode.

feature：

• Used in conjunction with pH glass electrodes to provide a stable potential reference.

• Usually filled with electrolyte (such as KCl) and in contact with the test solution through porous ceramics or glass fibers.

• The design may have anti pollution or corrosion resistance characteristics.

application：

• Used together with pH glass electrodes for precise measurement of pH values.

• Suitable for laboratory, industrial field, or field measurements.

maintenance：

• Regularly check the electrolyte level and replenish it in a timely manner.

• Clean the porous interface of the reference electrode to avoid blockage.

The matching use of GA151I and SE23I

• working principle：

• The pH glass electrode (GA151I) detects the concentration of hydrogen ions in the solution and generates a potential signal.

• The reference electrode (SE23I) provides a stable reference potential to ensure measurement accuracy.

calibration：

• Before use, standard buffer solutions (such as pH 4.01, 7.00, 10.01) should be used for calibration.

• Precautions：

• Avoid electrode contact with strong acids, alkalis, or corrosive substances.

• Clean the electrodes promptly after measurement to avoid contamination.
