What is Redox
(ORP)?
Oxidation-Reduction Potential (ORP)
or Redox potential measurements are used to monitor chemical
reactions, to quantify ion activity, or to determine the oxidizing
or reducing properties of a solution. ORP is a measurement of the
electrical potential of a redox reaction and serves as a yardstick
to judge how much oxidation or reduction takes place under existing
conditions. ORP electrodes measure the voltage
across a circuit formed by the measuring metal half cell and the
reference half cell. When the ORP electrode is placed in the
presence of oxidizing or reducing agents, electrons are constantly
transferred back and forth on its measuring surface, generating a
tiny voltage.

Measurement, please visit our

How Can Redox be
Measured?
Redox can be measured using the millivolt
mode of a pH meter. In the laboratory a bench pH Meter would
be used, in outdoor and field applications a portable pH Meter
is preferred and for plant and process applications an online pH
controller would be used.

Waterproof Portable:
The CyberScan ORP/pH Meters are an ideal choice for anyone requiring
to take ORP measurements in rugged outdoor field work or in situ
Plant and Process applications - being waterproof and robustly
built, the chance of accidental damage is virtually eliminated.
Not only is this instrument waterproof but in the event of
accidentally dropping it into liquid, it will float to facilitate
easy retrieval.
