Method for testing ion selective electrodes in continuous measuring systems |
摘要 |
The membrane of an ion selective electrode is tested for damage while it is being used for continuous measurement by sending a test current through the electrode system and measuring the voltage change produced. If the voltage change does not reach the value expected with an intact high resistance electrode, a defective electrode is indicated. A reverse current of the same magnitude and duration is then sent through the electrode system.
