Titanium Solution Ground PH Electrode With NTC10K Temp. Unit For Industrial Water

The reference electrolyte has a connection to the sample through the junction, as it serves to close the electrical circuit in the electrode.

A good reference electrolyte must have certain qualities.

The reference electrolyte must have good electrical conductivity and be chemically neutral. Since some electrolyte will typically leak into the sample during measurement, it is also important the electrolyte not react with the measurement solution.

The ions of an electrolyte solution must also be equally mobile. If ions in the electrolyte solution diffuse at different rates, an electrical potential (i.e. diffusion potential) can form due to the division between the positive and negative charge. This unwanted potential can be quite troublesome when measuring pH. With some ions (e.g. K+ and Cl-), the differences in diffusion speed are small, resulting in a much smaller diffusion potential.

Potassium chloride (KCl) possesses all of these qualities. As a result, KCl is the most commonly used electrolyte solution.

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.
