Oxidation-reduction potential (ORP), also known as REDOX, is a measure of the cleanliness of water and its ability to oxidize or reduce.
Oxidation is the loss of electrons, so oxidizers take electrons from other molecules. Reduction is the gaining of electrons, so reducers donate electrons to other molecules.
The
oxidation-reduction potential is measured as a single voltage in millivolts
(mV). Oxidizing agents have a positive ORP value, while reducing agents have a
negative ORP value. Our ORP
sensor has the feature a double junction technology to protect the reference
cell from contamination by sample components. Reliable performance in demanding
applications: The flat sensing face is self-cleaning and resists breakage, for
minimal maintenance. Output options include:
4-20 mA or MODBUS/RS485 output. Versatile design for many applications:
3/4" NPT threads on both ends for submersion or inline mounting. Since ORP
sensors have both 4-20 mA analog and Modbus digital outputs, they are well
suited for direct connection to our NTM multiparameter system. No secondary
transmitter is needed.
