The electrolysis electrode is not clean； The surface finish is not good enough; the electrode needs to be cleaned ； Or reasons such as the instrument being used for a long time or the solution in the electrolysis cell being too thick.
Online analytical instruments require routine maintenance: they need to be checked at regular intervals (for pre-treatment and the probes), and calibrated periodically. To ensure that these instruments function properly, it is essential not to wait until problems arise before taking action. The routine maintenance cycle is determined based on the type of online analytical instrument and the experience in handling it.
Air getting in is the main reason
Measure the electrolyte and add it to the standard range. Maintain level
Judging from the scene, it’s possible that the testing was not thorough enough, or there wasn’t enough electrolyte
