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. Does this pH electrode have a temperature compensation function?A: As the temperature of the aqueous solution changes, the concentration of hydrogen ions andhydroxide ions ionized from the aqueous solution will also change. The measured PH value is also constantly changing. If you need to get a more accurate measurement value, you must increase the temperature detection of the aqueous solution, perform temperature compensation or 25°C conversion.We have three basic models according to the packaging method of the temperature unit. 4. What is the wire length of the pH electrode?A: The lead wire of this electrode is 1m 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 electrode 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.
