saturated calomel electrode

[′sach·ə‚rād·əd ′kal·ə‚mel i′lek‚trōd]
(physical chemistry)
A reference electrode of mercury topped by a layer of mercury (I) chloride paste with potassium chloride solution placed above; easier to assemble than the normal and the one-tenth normal (referring to the concentration of KCl) calomel electrodes.
