Potassium Sensor

Each sensor requires a sensor cable to connect to LabMate+ or Tablet+. Sensor cable sold separately.

This Potassium Electrode is a PermaFil (non-refillable) Ion-selective electrode, with a sealed, gel-filled reference chamber. No reference fill solution is required. The electrode is used to conduct water quality studies by measuring Potassium ions found in aqueous solutions.
