Use and Maintenance and Precautions
1. Remove the electrode protective sleeve before testing(the solution in the sleeve is 3MKCL If there is a crystal leaching phenomenon, this is a normal phenomenon and will not affect the use of the electrode)
2. Observe whether the inside of the sensitive bulb is fully filled with liquid. If you find bubbles, slowly shake the electrode downward (like a thermometer) to remove bubbles from the sensitive bulb. Otherwise, the accuracy of the test.
