Indicating half cell electrodes transmit one half of a full electrochemical reaction. Electrodes include pH electrodes, reference electrodes, and more. For viscous solutions, use the Thermo Scientific™Orion™9162BNWP Low Resistance pH Electrode. For results three to five times more accurate compared to conventional electrodes, choose the Thermo Scientific™Orion™8101BNWP ROSS™Half-Cell Electrode.
