Cleaning of the electrode
Use clean drinking water for cleaning the electrode.
A 10% hydrochloric acid solution can be used for cleaning if the electrodes are
greasy. Protein coatings are removed with Pepsin cleaning fluid.
Electrode lifetime
The expected lifetime of the electrodes is dependent of the measurement. The
lifetime is given with reservation as the physical conditions as well as the
temperature, pressure and pollution of the fluid has great influence on the
stated lifetime.
The lifetime is based on
77° F / 25° C , but if the temperature is doubled, the
lifetime is halved in worst case!
pH electrodes in purifying plants for ordinary household waste-water lasts
approximately one year, whereas the lifetime of pH electrodes in industrial
plants is dependent on measuring application and the process. Redox
electrodes have a lifetime of approximately two years, depending on cleaning
intervals.
