Tips: How to determine the conductivity electrode constant?
According to the formula K = S / G, the electrode constant K can be obtained by measuring the conductivity G of the conductivity electrode in a certain concentration of KCL solution. At this time, the conductivity S of the KCL solution is known. Because the concentration and temperature of the measuring solution are different, and the accuracy and frequency of the conductivity meter are also different, a large error sometimes occurs in the conductivity electrode constant K. And the electrode constant may also change after a period of use. Therefore, the electrode constants of newly purchased conductivity electrodes and conductivity electrodes after a period of use should be re-calibrated.
Pay attention to the following points when measuring the conductivity constant of the conductivity electrode:
- The supporting conductivity meter should be used for measurement, and don’t use other type of conductivity meter.
- The temperature of the KCL solution should be preferably close to the temperature of the actual measured solution.
- The concentration of the KCL solution should be preferably near the concentration of the actual measured solution.
