PURPOSE:To prevent the inflow of blood cells into a reference electrode and to decrease electrical noise in the stage of measurement by making diametrally the same and horizontal the salt bridge from a containing part for a potassium chloride soln. up to a liquid jucntion part and providing an electrode for grounding and reference electrode as internal electrodes. CONSTITUTION:The salt bridge 31 up to an inflow path 11, containing part 91 and liquid junction part 41 for the potassium chloride soln. is made diametrally the same and horizontal. the containing part 91 is formed to a crank shape and the internal electrodes 61, 62 are fixed. The electrode 61 is used as the reference electrode and the electrode 62 as the electrode for grounding. Blood which is a liquid to be examined is passed through a tube A to the part 41 and is passed to a tube B. The flow tube for the potassium chloride soln. is thus provided equally in the diameter and horizontally and therefore the growth of foam and the inflow of the blood cells into the internal electrodes are obviated. Since the electrode for grounding is provided, the noise is decreased and the stable reference electrode is obtd. |
