Potassium ISE BNC

The Vernier Potassium Ion-Selective Electrode BNC Connector is a BNC-terminated electrode used to measure the concentration of potassium (K⁺) ions in aqueous samples. Use with Vernier interfaces requires the Electrode Amplifier. Also compatible with Go Direct^® Electrode Amplifier and Go Direct^® Ion-Selective Electrode Amplifier.
