pH

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
