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. CA Residents: Prop 65 WARNING(S) Read More
