  • pH sensor refill solution
    Refillable glass pH electrodes contain liquid electrolyte solution, which serves to close the electrical circuit in a pH electrode. The electrolyte solution must have electrical contact with the solution being measured. Contact is made via a semipermeable junction, which permits a consistent outflow of liquid electrolyte.  Over time, electrolyte is depleted and should be replaced.
    • 3.5 M liquid KCl for Sensorex model pH3000
    • 3.5 M liquid KCl/AgCl for Sensorex model pH1400
