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.

Single-junction models with Ag/AgCl reference element
For routine pH and titration measurements with small samples and small vessels, where separate half-cell electrodes may be impractical
Fast response despite temperature changes plus extra durability
Can be optimal for lab use and precise Q.C. measurements.
Thermo Scientific™ Orion™ Double Junction Semi-Micro Electrodes provide reliable and accurate measurements of routine samples. They are available in chemically resistant glass bodies and best suited for measuring general samples as small as 0.2mL, in test tubes and small containers.
Thermo Scientific™ Orion™ Sure-Flow™ electrodes are built with a unique free-flowing liquid-to-liquid junction that simplifies measurements of dirty or viscous samples by helping to prevent clogging, making them easy to clean.
Thermo Scientific™ Orion™ ROSS Ultra™ Glass Semi-Micro Electrodes provide optimum accuracy and unmatched response in samples of varying temperatures. They are available in chemically resistant glass bodies and are best suited for measuring samples in test tube and small containers.
Single-junction Ag/AgCl flat surface model
Ideal for critical samples such as suspensions or samples of unknown composition. Mettler Toledo Expert Series pH and pH/ATC Combination Electrodes with open junction puts the reference electrode in direct contact with the measured medium, eliminating the possibility of contamination or blockage.
Thermo Scientific™ Refillable Orion™ ROSS Ultra Triode™ 3-in-1 pH/Automatic Temperature Compensation Electrodes combine the precision and speed of response of the ROSS Ultra™ line with a built-in ATC. Best suited for use in strong acids/bases, pH > 12 or pH < 2, food & cosmetic emulsions, pure water...
