The pH meter electrode is the only part of the instrument that comes into direct contact with the sample. Electrode function therefore has the strongest influence on measuring precision and accuracy. However, electrodes can suddenly begin performing badly. Fortunately, researchers can restore electrode performance with a few maintenance procedures.
