The accuracy of the conductivity meter is a very important factor for reliability. Long-term use will cause changes in the conductivity cell constant and motor indication value of the conductivity meter, so regular calibration is required. The conductivity meter standard detection box can calibrate the error of the conductivity meter used in ships, reduce the instrument error caused by the aging and failure of components, determine the cause of the error, restore the design performance of the instrument, and maintain a good measurement performance for the conductivity meter accuracy. So how should the conductivity meter standard test box be calibrated? The calibration method of the conductivity meter standard test box is as follows:
