Ohaus STREF1 Glass Starter Reference 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. Reference electrodes have a stable and well-defined electrochemical potential. A measured potential in an electrochemical cell is determined against a defined potential value of a reference electrode. Specifications: Description: Silver/Silver Chloride (Ag/AgCl) E vs. SHE (Standard Hydrogen Electrode) (V): 198 Connector: 2 mm Banana Dimensions (Shaft): 110 x 12mm Cable Length: 1m CARE AND USE Maintenance of reference electrodes can help avoid stability problems and keep them in proper working condition. Check that the reference electrode compartments are filled with electrolyte solution and the junction is not blocked. Starter Series Electrodes Data SheetSTREF1 Manual
