0~100℃ pH electrode with High temp. resistant for Sewage water

The pH electrode determines the accuracy of pH measurement, so pH electrode status is critical. Therefore, in order to prolong the life of the pH electrode and the accuracy of the results, the daily maintenance of the electrode is very important. If the electrode is not cleaned after use or electrode maintenance is neglected for a long time, the electrode will no longer be accurate and the accuracy of the system will quickly degrade. This is manifested by a gradual decrease in the slope of the electrode. When the slope drops to 50mV/pH (equivalent to 85% of the slope) or the zero point exceeds ± 30 mV, some treatment methods can restore the electrode to the expected performance, but for the accuracy of the measurement results, it is necessary to replace a new electrode.

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

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.
