Installation
Installation instructions Do not install the electrodes upside down. The angle of inclination must be at least 15° from the
horizontal. A smaller inclination angle is not permitted as it could cause an air bubble to form in the
glass sphere and prevent the inner electrolyte from completely wetting the pH diaphragm.
NOTICE
Before screwing in the electrode, make sure the threaded connection of the assembly is clean
and runs smoothly.
‣
Screw in the electrode finger-tight (3 Nm)! (Data apply only if installing with Hauser
assemblies.)
