Analog PH Electrode With PT1000 Temperature Compensation For Industrial Water

pH measurement with a glass pH electrode relies on the measurement of a voltage.

In order to measuring the voltage, two points with different electrical potential values are needed. The reference electrode is designed to maintain a constant electrical potential that is independent of the sample composition and temperature.

In contrast, the hydrogen ion selective electrode (ISE) with glass membrane provides an electrical potential that is dependent upon the activity of hydrogen (H+) ions in the sample solution.

Therefore, both the reference electrode and the hydrogen ISE are needed when determining pH.

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.
