A good reference electrode that fits into the cells made by BVT perfectly.

The calomel electrode is a reference electrode based on the reaction between elementary mercury and mercury(I) chloride. The aqueous phase is in contact with the mercury and the mercury(I) chloride (Hg2Cl2, “calomel”) is a saturated solution of potassium chloride in water. The electrode is linked via a porous frit to the solution in which the other electrode is immersed. The tube is hollow with a hole in the wall for inserting KCl solution. The Hole is covered by a rubber band. This Reference classic electrode (RCEc) is designed for measurements with  the cells TC4, TC5 or TC6, that can alll be used with the Minithermostat offered by BVT.
