4.3.3 Chemical cleaning
The chemical cleaning system is based on periodically spraying of a cleanser on to the
glass membrane of the electrode. The cleanser to be used, the cleaning frequency, etc. are
highly dependent on the liquid to be measured. The cleaning period and frequency can be
adjusted on a control unit. The mounting procedure is shown in figure 4.5.
