Analog Type Glass PH Probe With 0~100℃ Temperature Resistance For Clean Water
In the glass sensor measurement method, the known pH value of the reference solution is determined by using a glass electrode and a reference electrode. Measure the potential difference between the two electrodes. The pH of the liquid in the glass electrode is usually 7. Potentiometric methods determine pH by using the electrical potential of pH-sensitive electrodes as a measurement signal.

FAQ
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 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.
