Horiba pH Half-Cell & Reference Electrode activated carbon 24 Total Algae-Phycocyanin Sensor (FreshSeparate half cell and reference electrodes for HORIBA meters set up as two electrode systems. A combination electrode packages both halves into one body; a two electrode system keeps them apart, which lets you replace only the part that has failed and lets you choose a reference junction suited to a difficult sample. A pH measurement is a voltage between two half cells: the glass electrode responds to hydrogen ion activity, and the reference
