1,070,674. Reference electrodes. OKURA DENKI KABUSHIKI KAISHA. Feb. 9, 1965 [March 10, 1964], No. 5574/65. Heading G1N. A reference electrode has its interior sealed off in liquid light manner from the liquid under test, electrical contact being made through a carbon or semi-conductor member 7. The member may be made of highly pure carbon, carbon containing impurities, silicon or germanium. In Fig. 2 (not shown) a calomel or Ag-AgCl electrode 2 is immersed in a saturated K Cl solution 3. In Fig. 3 (not shown) a lead 5 connects directly with the interior surface of the carbon or semiconductor member. The reference electrode may be used with a glass electrode for pH measurements or with a metal electrode for measuring potentials of oxidation-reduction systems. |
