1 Inch NTP PH Electrode With Self-Cleaning Connector For Industrial Water
Composite electrodes are more convenient to handle than two separate half-cell electrodes and are very common today.
In the composite electrode, the pH-sensitive glass electrode is located in the middle, and the periphery is surrounded by a reference electrode filled with a reference electrolyte. The pH electrode and reference electrode part of the composite electrode have the same function as the independent electrode, the only difference is that the independent electrode is integrated into one electrode, which is more convenient to use. The use of a separate electrode is only recommended when the service life of the pH electrode and the reference electrode is very different. A more convenient electrode is to add a temperature probe to the composite electrode, so that temperature compensation can be easily performed. This electrode is called a 3-in-1 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 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.
