1. Safety instructions
To avoid permanent damage to the redox electrode, it
must always be kept in the storage solution that is
provided!
•
Do not allow it to become contaminated by:
mineral deposits
organic oils or greases
•
Do not allow the electrode covering to come into
contact with organic silicones!
•
The electrode must be stored at a temperature in
the range between +10°C and +35°C
2. Description
The redox (reduction/oxidation) electrode, also called
the ORP (Oxidation-Reduction Potential) electrode,
consists of an outer platinum half-cell, which
measures a property of the solution that is being
tested, and an inner half-cell containing an Ag/AgCl
gel as a reference.
The platinum electrode is capable of either taking up
electrons (reduction)
(oxidation). It does not itself react with the medium.
Redox Sensor U11337
or releasing electrons
The sensor box together with the redox electrode is
used for the measurement of redox values in aqueous
solutions.
A storage solution (not a buffer solution!) is supplied
with the redox sensor.
A reference solution consisting of a saturated buffer
solution of quinhydrone with a pH value of 7.00 is
available separately (item number U11352).
The redox sensor box is recognised automatically by
TM
the 3B NETlog .
