Caution on Use
Safety Precautions
Points of concern
Do not shock the electrode.
Do not measure chapped or cracked electrode. Replace
such electrode with a new one.
Do not allow the connector to come in contact with water
or unclean hands. If not, accurate measurement cannot
be performed.
Always use the 3.33 mol/L-KCl solution (model 300)
internal solution for reference electrode.
If the responsive glass membrane or liquid junction is
very dirty and cannot be washed clean using pure water,
cleanse it depending on dirt condition.
(Refer to " Maintenance " (page 4).)
Avoid continuous use of this electrode at acidic or
alkaline concentrations above 0.1 mol/L. Using the
electrode under these conditions may harm
performance and shorten the life of the electrode.
Do not measure the solutions which contain fluoride ion,
which may corrode the glass electrode.
Do not suddenly immerse the electrode in samples
where the temperature variation is 50C or more.
Silver chloride can be detected inside the responsive
glass membrane. However, it will not cause any
performance problem.
Do not use the electrode in any place where usable
temperature is out of the specified range.
White crystal can adhere to the internal solution filler
port or protective cap after storage of the electrode.
However, it will not cause any performance problem.
This equipment conforms to the following standards:
RoHS: EN50581
9. Monitoring and control instruments
CAUTION
Chemical solution
The internal solution in the electrode uses potassium chloride
(3.33 mol/L-KCI). If the internal material comes in contact with the
hands or skin, wash immediately with water. If the internal solution
comes in contact with the eyes, flush with a large amount of
running water, then seek medical advice.
Glass fragments
Glass fragments can cause injury.
The outer tube and tip of the electrode are made from glass.
Be careful not to break them.
