    Analog Signal Glass PH Sensor With High Temperature Resistance For Pure Water

    Analog Signal Glass PH Sensor With High Temperature Resistance For Pure Water

    A pH electrode, the part of a pH meter that is in contact with the solution being measured, is a device used to determine the potential value of a specific ion of the solution. The pH probe sensor is a pH composite electrode with a glass shell. Glass housing is more corrosion resistant than plastic housing.

    The glass head of the pH probe sensor is blue low-impedance hemispherical. It has high strength and does not break easily, it helps enhance the accuracy of measurement.

    The reference electrode of the pH probe sensor is Ag/AgCl, reference filled saturated KCL + excess KCL crystals for long service life. It has the advantage of low maintenance and suitable for online measurements in demanding applications.

    The reference system is a double salt bridge design, and the ceramic porous cores have a smooth response, no drift in potential, and good stability. The pH probe is equipped with standard 3m low noise leads.

    1. What is themeasurement principle of this pH electrode?
    The pH value potentiometric method uses the potential difference of glass electrodes for pH measurement.

    2. How is this glass pH electrode composed?
    The pH electrode is usually composed of an indicator electrode and a reference electrode.

    3. How to judge the pH of the solution?
    A: If the internal hydrogen ion concentration of the pH glass bulb is lower than the outside, the measured solution is recorded as acidic and the pH value is lower than 7; if the two are the same, the solution is neutral and the pH value is equal to 7; if the internal hydrogen ion concentration is higher than externally, the measured solution is alkaline and the pH value is higher than 7

    4. What is the wire length of the pH electrode?
    A: The lead wire of this electrode is 3m by default, other lengths need to be customized, contact our customer service, the price will vary with the change of length.

    5. How often must the pH sensor be calibrated?
    A: Depends on the type of sample:
    Dirty samples and non-aqueous samples require more frequent calibration.
    Depends on the required accuracy:
    For very accurate measurements, at least daily calibration is required.
    Depends on the quality of the electrode:
    Old electrodes require more frequent calibration.
