If the transmitter does not show the correct value when put into the buffer
solution, the electrode must be exchanged.
Cleaning of the electrode
Use clean 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 (item
number 163020).
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 25° C, but if the temperature is doubled, the
lifetime is halved!
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.
