Abstract
An Electrochemical biosensor readout meter which can do selectively quantitative analysis of sample of living body such as blood sugar, cholesterol and other elements in blood is disclosed. It is an object of this invention to provide electrochemical biosensor readout meter which has no distortion in peak current and can be manufactured in a low cost. In a preferred embodiment of present invention, a voltage converting means (OP2) is set to convert peak current which occurs at 3rd voltage applying time (t3) into voltage with no distortion and an amplifier (OP3) is set to make digital voltage signal at measuring time (t4) lower than reference voltage of A/D converter.
