Warning

Read before using instrument!!!
When measuring food the electrodes should always be first cleaned
with clear water so that buffer solutions, storage and refill solutions do
not enter the food cycle. If the electrode is damaged during a
measurement on food you should remove the food in question along
with the broken electrode.
The housing of the electrode is made partially of
glass: RISK OF BREAKAGE!
The membrane of the electrode should always be kept damp.
Use the protective cap when not measuring.
The probes are not suitable for measurements in solutions with a large
organic content (e. g. ether, ester, ketone etc.) or aromatic or
halogenated hydrocarbons.
Inappropriate storage, special environments (e.g. environments
containing sulphide or protein, highly-alcaline environments), high
temperatures or large changes in pH or temperature can influence the
life of pH electrodes.
Never leave buffer solutions open during storage! Never calibrate in
buffer bottles! Do not pour used buffer solutions back into the
storage bottle.
Never use destilled water for storing the pH electrodes.
Spilled electrolyte solution should be wiped up immediately with a
damp cloth. Electrolyte solution can damage metallic and electrical
parts.
General note:
Testo uses redox as a synonym for ORP.
