Sensorex plastic body pH electrodes are constructed of epoxy. Bulb protection is standard. See pH Electrode Selection Guide for more information.

Glass Body electrodes feature ruggedized hemispherical bulbs as their standard feature. See pH Electrode Selection Guide for more information.

Research Grade electrodes utilize our pHASE technology for rapid thermal equilibration and stability.

Calomel Free pH electrodes offer a mercury free replacement for calomel electrode applications such as biological samples.

3-in-1 electrodes incorporate an Automatic Temperature Compensation (ATC) element and can be supplied to match your pH meter's requirements.

Flat Surface electrodes are used for viscous or oily samples. When installed in one of our micro liter flow cells, they are perfect for HPLC, FIA, and other Low Volume sample analysis.

Spear Tip piercing pH electrodes are designed for demanding penetration measurements. Use them to stab into soil samples, cheese, or even raw meat!
