Description
DOCUMENTS

Redox potential and pH measurements with separate electrodes require the use of a measurement electrode and a reference electrode. The latter will retain a constant, stable potential during the measurements.
– Mercurous sulphate (Hg/Hg₂SO₄) reference electrode.
This comprises a glass tube in which a drop of mercury and mercurous sulphate (Hg2SO4) are placed in contact with a platinum wire. The reference element is filled with a saturated potassium sulphate solution (K₂SO₄).
– Equipped with a porous ceramic junction which allows the reference electrolyte to “sweat” but prevents it from flowing freely.
– Reference electrode used in potentiometry, notably for certain assays where a calomel electrode cannot be used, such as argentometric assays in which the Ag⁺ ions may react with the chloride ions to form a precipitate of silver chloride (AgCl).
The choice of the reference electrode depends above all on the experimental conditions for your measurements.
This reference electrode must be used with a measurement electrode (BAG1 or XAG1) for correct ORP measurement.
– Versions with various connection technologies are available for adaptation to all your instruments.
