11.4 Measuring cells
PLEASE NOTE
Note the service life of the measuring cells
The service life of the measuring cells is approx. 12 to 15 months,
whereby the storage time must be taken into account at 50 %. If the
service life is exceeded, this may distort measurement results.
ð
Note the printed date of manufacture and replace obsolete measur-
ing cells in good time.
The service life of the single-rod measuring cells depends on the operat-
ing conditions and the water properties (e.g. corrosiveness, grease etc.).
In normal conditions the service life will be 12 – 15 months, which in-
cludes 50 % storage time. The counter electrode of the disinfection meas-
uring cell can have a service life of up to several years, depending on the
corrosiveness and the abrasiveness of the water. It must only be replaced
when heavy signs of wear appear.
