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

PH glass electrode.
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.
Laboratory pH measurement.
Industrial process control (such as chemical, pharmaceutical, food processing).
Environmental monitoring (such as water quality analysis).
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.

Reference electrode.
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.
Used together with pH glass electrodes for precise measurement of pH values.
Suitable for laboratory, industrial field, or field measurements.
Regularly check the electrolyte level and replenish it in a timely manner.
Clean the porous interface of the reference electrode to avoid blockage.
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.
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.
