Abstract
Disclosed herein is an electrochemical biosensor measuring device which comprises at least two photodiodes for emitting light beams at regular time intervals in a sequential manner, with the insertion of an electrochemical biosensor thereto, and a detector for sensing the emitted light beams, thereby identifying the production lot information recorded on a production lot information identification portion on the electrochemical biosensor. Thus, the device enjoys economic advantages of not requiring a high-priced optical filter in detecting the light absorbed through or reflected from the production identification information recorded in biosensor and a complicated software algorithm to recover the production lot information. Also, the measuring device automatically identifies the production lot information recorded on the biosensor, so that the frequency of inconvenience and error that occur when a user personally inputs the production lot information of the biosensor can be reduced, with the result that the measured values can be conveniently and accurately acquired.
