A sensor 13 is inserted into a connector 14. A constant voltage required to obtain a response current is applied across the connector 14 by a voltage applying source 15 at timings required. A response current of the sensor 13 inserted into the connector 14 is converted into a voltage by a current-to-voltage...http://www.google.fr/patents/US5266179?utm_source=gb-gplus-shareBrevet US5266179 - Quantitative analysis method and its system using a disposable sensor
