Analog Signal Glass PH Sensor With High Temperature Resistance For
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

1. What is themeasurement principle of this pH electrode?
A: The pH value potentiometric method uses the potential difference
of glass electrodes for pH measurement.
2. How is this glass pH electrode composed?
A: 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
Depends on the required accuracy:
For very accurate measurements, at least daily calibration is
Depends on the quality of the electrode:
Old electrodes require more frequent calibration.
