Potassium Ion-Selective Electrode BNC
Connect the Potassium Ion-Selective Electrode BNC to our electrode amplifiers to measure the potential (mV) and calculate the concentration of potassium (K+) ions in aqueous samples.
Description
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.
