Refillable sensors can maintain accuracy for longer time periods. This sensor type requires re-filling with KCl solution when the liquid level is about 1” below the re-fill hole. To do this, slide the protective outer sleeve up to expose the filling hole and fill the electrode to the hole level with KCl (potassium chloride) solution.

Extend the life of your pH and ORP sensors by using the Sensorex pH electrode storage solution. When the sensor is not in use, place the sensor glass measurement area into the storage solution. The pH electrode storage solutions are supplied in pints (473 ml).

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
