NTC10K Temperature Compensation Glass PH Sensor For Dirty Water
For our glass electrodes, the glass membrane is fused to form a pH sensor. The glass membrane is filled with a buffer solution of pH = 7. This design creates an environment where H+ ions are continuously combined on the inside of the glass membrane, while the outside of the glass membrane is exposed to the sample, where there are varying amounts of H+ ions. The difference in H+ ions produces a potential that is read relative to the stable potential of the reference electrode.

Brief introduction:
- The glass head of the pH probe sensor is 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, filled KCL colorless high-temperature gel. The gel electrode is an upgraded and improved version of the liquid electrode that is low maintenance and suitable for online measurements in demanding applications and can last long after several cleanings and disinfection.
- A porous diaphragm has the characteristics of fast penetration, fast response, not easy to block, and easy cleaning.
- A mounting thread of size PG13.5 is provided at the end of the electrode for easier installation.
- The pH probe is equipped with standard 5m low noise leads.
Aplication:

Chemical,petroleum,paper,food and medicine,PCB manufacturing,etc.
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 5m 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.
