How to Order a
Redox Electrode
(1) Choose Electrode Model.
If the electrode needs to fit an existing cab le, check the cable con-
nector and note its color. If the ca ble connector is black and has an
S8 con nector, use the F-915 or F-935 Redox FermProbes. If the cable
connector is red or orange and has a K9 connector, use the F-995
Redox FermProbe.
(2) Choose Electrode Length.
If you have already chosen a housi ng, select an electrod e length
with the same Class designation as the hous
ing. For more informa-
tion on s election of housings, see pages 18-21. The housing orde r-
ing information box also lists the correct electrode length to order. If
you have no t already cho sen the housing, please review the recom-
mendations next to each electrode model below.
(3) Confirm
Cable Length and Connector.
Model F-915, F-935, and F-995 Redox electrodes require disconnect
cable and connector assemblies. See pages 70–73.

What is Redox (ORP)?
The terms are interchangable in meaning:
Redox = Oxidation-Reduction Potential (ORP)
The term Redox is more commonly used for bioprocess
applications in Europe and the U.S.
The term ORP is more commonly used for industrial
chemical process applications in the U.S.
The redox potential of a media is related to the
overall availability of electrons in the media,
specifically the ratio of positive and negative ions
in the solution. Note that redox measurements
vary significantly with changing pH.
