Abstract:
A concentration measuring apparatus and a test strip which is applied thereto, the test strip including on a base material a reaction reagent for reacting with a liquid test sample, a positive terminal, and a negative terminal, the terminals electrically detecting a concentration of a specific component in the liquid test sample based on the reaction of the reaction reagent, the concentration measuring apparatus comprising a positive electrode and a negative electrode to be electrically connected respectively to the positive terminal and the negative terminal of the test strip, thereby measuring the concentration of the specific component in the liquid test sample via the positive electrode and the negative electrode,the concentration measuring apparatus further comprising a reagent identifying electrode for identifying a type of the reaction reagent formed on the test strip which measures the concentration of a sample applied to the concentration measuring apparatus, with the reagent identifying electrode being provided separately from the positive electrode and negative electrode; a first identification device for feeding information corresponding to the test strip based on the reagent identifying electrode being connected with the positive electrode only when the test strip is applied to the concentration measuring apparatus, and a second identification device for identifying the test strip based on the information fed from the first identification device.
