These standard Thermo Orion Combination pH Electrodes are available in four styles for general purpose lab work. The Sure-Flow combination electrodes have a free-flowing liquid-to-liquid junction that resists clogging. Simply press the cap to flush the junction area. Ideal for dirty or viscous samples.

Triode 3-in-1 electrodes contain the pH electrode, reference, and temperature probe in one probe. Durable epoxy body.

Green electrodes are the first electrodes to meet all RoHS requirements, and therefore contain no hazardous components. Free of lead and mercury, allowing easy disposal.

All electrodes include a 1-m cable and BNC connector.
