Sodium

The SMD foil sodium electrode Na-01 is designed for electrochemical, potentiometric determination of Na+ in liquid or moist samples when combined with a reference electrode. The readings are taken by measuring the open circuit potential/voltage between both electrodes via high resistivity voltage measurement electronics (see example circuit below). Potential (E) and sodium concentration have a linear relationship in the operating range of 100 µM to 1 M. The sodium concentration of an unknown analyte solution can be calculated using the pre-determined slope and an offset E0 value, which can be determined by measuring the potential in a calibration solution of known sodium concentration. Once used, the sensor must be kept hydrated for further application and must not allowed to dry out.Datasheet:Datasheet_addsensors_SMD_Na01_eng.pdfDesign / User Manual:Design-Setup-Guide.pdf (addsensors.com)
