For industrial applications and particularly for automatic process measurements it is of the greatest importance that the sensistive part of a glass electrode and the diaphragm of areference electrode are kept clean. Often it is not practical to interrupt a process for cleaning the electrodes, an accurate indication is required over a long period, replacing the electrodes is difficult, etc. Then an automatic cleaning mechanism may be the solution.
Yokogawa manufactures two different cleaning systems for pH and/or ORP (Redox) measurements:
- Chemical cleaning.
- Mechanical cleaning.
(The cleaning elements have standardised dimensions formounting in flow-, insertion and immersion fittings.)
