pH electrodes have two main elements; a sensing half-cell and a reference half-cell. Both of these are required to complete the pH circuit that will result in the pH measurement you are looking for.
General Laboratory Supply offers combination pH electrodes made from epoxy or glass, sealed or refillable with single or double junctions. Choose from major brands such as Thermo Orion or Oakton Instruments.
The Thermo Orion Triode™ eliminates the need for a separate ATC probe by embedding a thermistor-type ATC in the tip of the electrode. One lead running from the electrode to the meter makes it easier to work with, especially in field applications. (Sample Photo Displayed.

The most common cause of error in pH measurements is temperature. The slope of a pH electrode is highly dependent on temperature and pH buffer values and sample values change with temperature. For the most accurate results an ATC probe is always recommended. The epoxy body Thermo Scientific® Orion™ ATC probes (PH4341-1/-3) are not recommended for use in organic solvents, but may be used on an intermittent basis in methanol or ethanol. Glass body Orion ATC probes (PH4341-4/-7) are preferred for use in solutions containing organic solvents or at temperatures over 80°C.

Thermo Orion™ Electrode Adaptor Cables allow conversion of an electrode that does not have the correct termination for a particular meter to be adapted for that meter. Adaptor cables allow conversion of electrodes with one connector to the required connector for a certain meter. For use with meters that have BNC, US standard, certain LEMO, British, E DIN, Radiometer, 2mm reference pins or just a stripped lead inputs. Electrodes must have a US standard, screw cap, Karl Fisher, or BNC connectors. (Sample Photo Displayed.
