pH, ORP, and Titration, Combination Electrodes

Combination electrodes feature both a reference electrode and sensing electrode combined into one sensor. Triode™ electrodes include a second integrated connection for ATC (automatic temperature compensation). pH or ORP (oxidization reduction potential or redox) electrodes are available in epoxy, glass, or rugged glass bodies. Titration electrodes can be either pH or ORP and are designed for use with Orion™ StarT™ series titrators.
