Caution on use
Safety Precautions
Points of concern
Do not give an excessive shock to the electrode.
Cracked or chapped electrode can be used.
Replace such electrode with a new one.
Avoid continuous measurement soaking in the strong
acidic or alkaline solution concentrated more than 0.01
mol/L. These solution may reduce the performance and
the lifetime of the electrode.
Do not to use the electrode in a solution in which
hydrofluoric acid (HF) is contained. Glassware will
corrode in the HF solution.
Avoid sudden temperature charge over 50°C on the
electrode. The sensor body might be deformed or the
glassware might be cracked.
Solid particles of silver chloride might be observed
floating in the inner solution of the responsive glass
membrane. This is not a problem and this will not affect
performances of the electrode.
Do not use (store) the electrode in any place where the
operation temperature (storage temperature) is out of
the specified range.
Body material is plastic. Do not use organic solvents
(such as acetone or toluene) .
