Objective: By deducing compute for solving electrode potential of gauging point in the exidimetric and reductometric titration method, raise accuracy of measurement. Method: According to Nernst-Peters equation deduces compute formula for solving electrode potential of gauging point in the oxidimetric and reductometric titration method, points out applicable range on different condition and illustrated by measurement of proportion to iron. Result: Use different formula on different condition avoid appearing error in the course of teaching or actual measurement. Conclusion: By discussing use range of formula using the oxidimetric and reductometric titration method can more accurately measure the proportion to iron in the hair or blood.
