Ohaus STORP2 Glass Refillable ORP Electrode The OHAUS Starter Series of electrodes are designed to produce exact results time and time again. They fit perfectly in the electrode holders on OHAUS bench meters as well as electrode clips on all OHAUS portable meters. Oxidation-Reduction Potential (ORP) electrodes test for the overall availability of electrons in a medium, specifically the ratio of positive and negative ions in the solution. They are also sometimes referred to as Redox electrodes. ORP is the only practical method used to electronically monitor sanitizer effectiveness and it is also commonly tested in water, such as swimming pools and aquariums. Specifications: Shaft Material: Glass Temperature Range: 0-100 ˚C Internal Reference Type: Ag/AgCl Refillable/Non-refillable: Refillable Reference Junction Type: Annular Ceramic Refilling Reference Electrolyte: 3M KCI Solution Dimensions (Shaft): 120 x 12mm Cable Length: 1m Temperature Sensor: No Connector: BNC Zero Potential Value: 86mV±15mV Grade Difference: ≥ 165mV CARE AND USE To ensure accurate measurements, it is important to keep the electrode clean. Contamination can cause inaccurate results and slow response times. Starter Series Electrodes Data Sheet
