The recommended reference electrode for our Chloride sensitive electrode ES-CL-1 is RE-K2SO4-1. This is a Hg/Hg₂SO₄ Reference Electrode which is recommended when the electrolyte’s chloride ion is not desired. This reference electrode is a suitable choice for neutral or acidic systems where it is necessary to avoid chloride ion pollution. It is prepared with reagent-grade mercury sulfate and saturated K₂SO₄ solution. The fill solution is saturated K₂SO₄ product name for fill is FS-K2SO4-1
