Functional sample SMD foil sensor K (Potassium) – K-01

The SMD foil potassium electrode K-01 is designed for the electrochemical, potentiometric determination of K+ in liquid or moist samples in combination with a reference electrode. The measured values are determined by measuring the open-circuit potential/open-circuit voltage between the two electrodes using high-impedance voltage measurement electronics.As this is a prototype functional model, there is no preliminary data sheet yet. You will receive a corresponding prototype performance results report when the item is delivered. Once used, the sensor must be kept hydrated for further application and must not allowed to dry out.Datasheet:Datasheet_addsensors_SMD_K01_eng.pdfDesign / User Manual:Design-Setup-Guide.pdf (addsensors.com)

Functional sample SMD foil sensor Na (Sodium) – Na-01

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)

Functional sample SMD foil sensor pH – pH-01

The SMD foil pH electrode is designed for electrochemical, potentiometric determination of pH in liquid or moist samples when combined with a second, reference electrode. The readings are taken by measuring the open circuit potential/voltage between both electrodes via high resistivity voltage measurement electronics. Potential (E) and pH have a linear relationship in the operating range of pH 5 to pH 9. The pH value of an unknown analyte solution can be calculated using the pre-determined slope and an offset E0 value, which could be determined by measuring the potential in a calibration buffer of known pH value. Once used, the sensor must be kept hydrated for further application and not allowed to dry out.Datasheet:Datasheet_addsensors_SMD_pH01_eng.pdfDesign / User Manual:Design-Setup-Guide.pdf (addsensors.com)

Stripe foil sensor pH-303

The Stripe foil sensor pH-303 is a foil sensor with electrodes for electrochemical determination of pH of samples. Our pH-sensor consists of two electrodes (a pH-sensitive and a non-sensitive Ag/AgCl reference electrode) on a transparent PET foil. The readings are taken by measuring the open circuit potential/voltage between both electrodes. Potential (E) and pH have a linear relationship (between the operating range of pH 5.5 to pH 10) so the pH of an unknown analyte solution can be calculated using the pre-determined slope and an offset E value (E0 determined by measuring the potential in a calibration buffer of known pH). The reference electrode and overall sensor can be used in analytes with different chloride concentrations thanks to a solid-state electrolyte layer. Once used, the sensor must be kept hydrated for further application and not allowed to dry out.Product includes:1 x Stripe foil sensor pH-303Datasheet:Datasheet_addsensors_stripe_pH_S-303.pdf

Stripe foil sensor potassium-601

The stripe foil sensor Potassium-601 is a foil sensor with electrodes for the electrochemical determination of the potassium value. Our potassium sensor consists of two electrodes (a K-sensitive and a non-sensitive Ag/AgCl reference electrode) on a transparent PET foil. The measured values are determined by measuring the open-circuit potential/voltage between the two electrodes. The reference electrode and the entire sensor can be used with analytes with different chloride concentrations thanks to a solid-state electrolyte layer. After use, the sensor must remain hydrated for further use and must not dry out.To evaluate the data, a connection can be established using our Device ion selectiv D-300. Alternatively, the data can be evaluated using ZiF contacting. The contact surfaces are provided with oxidation protection. The data given refers to the use of the sensor in combination with the device Ion selectivity D-300. The measured potential (in mV) is displayed, or if the sensor is calibrated (one-point software calibration at 21 °C or two-point calibration at other temperatures), the concentration K+ can be output.Product includes:1 x Stripe foil sensor potassium-601Datasheet:Datasheet_addsensors_stripe_potassium_S-601.pdf
