S020 - Refill Solution, Potassium Chloride (KCl) for Refillable pH Sensors

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.
