Abstract

In a quantitative analyzer for a biological fluid, e.g. a blood glucose level analysis, a sensor is inserted into a connector. A constant voltage required to obtain a response current is applied across the connector from a source 15 at required timings. The response current of the sensor is converted into a voltage by a current-to-voltage converter, and the value thereof is determined by a microcomputer.
The analysis results are displayed on a display unit. The system provides more reliable results than prior systems.
