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:

1. The supporting conductivity meter should be used for measurement, and don't use other type of conductivity meter.
2. The temperature of the KCL solution should be preferably close to the temperature of the actual measured solution.
3. The concentration of the KCL solution should be preferably near the concentration of the actual measured solution.
