ORP (Oxidation-Reduction) Electrodes
Available from Weiss Research, Inc.
Unlike pH electrodes which can be calibrated and adjusted by meters, ORP electrodes are difficult to be standardized by most pH/mV meters. Keeping constant reference potential is the key to successful ORP measurement. To fulfill this requirement, the ElectroJelly™ filled (sealed) electrodes were developed. ElectroJelly™ is a solid material with highly concentrated salt (most time it is KCl). Because the ElectroJelly™ can effectively hold reference electrode electrolytes against sample back-flow and contamination, the ElectroJelly™ filled (sealed) electrodes can easily accomplish stable reference potential, longer life and less calibration goal (compared to regular gel filled electrodes). The ElectroJelly™ filled electrodes are most suitable for the 24/7 monitoring applications with temperature cycling changes such as swimming pools, aquariums and industrial processing. It is even better when it is used under normal laboratory conditions.
