Device for measuring oxygen concentration of molten metal

摘要: A DEVICE FOR MEASURING OXYYGEN CONCENTRATION OF MOLTEN METAL BY USING AN OXYGEN CELL, WHEREIN SOLID ELECTROLYTE IS DIRECTLY OR INDIRECTLY COVERED WITH MATERIAL TO BE CARBONIZED IN THE METAL, SO THAT ELEMENT MAY GRADUALLY HEATED BEFORE COMING CONTACT METAL. ELECTRIC CONNECTION INDICATOR SIMULTANEOUSLY ACCOMPLISHED ITS MECHANICAL STANDARD GAS SOURCE. SPECIMEN CLEAN CAN COLLECTED FROM SUBSTANTIALLY SAME SPOT WHERE MEASURED.
