ABSTRACT:
An electronic sensor is described that includes a sample receptacle and a data storage device. The data storage device is powered by a pair of half cells on the sensor. The half cells contain ion solutions that are also used to calibrate the sensor. As the sensor is placed within a sensor data reader, the data stored on the data storage device is transferred to the reader along with measurements of the voltage potential between the half cells. The reader thereafter calculates a calibration slope curve for the sensor. The calibration slope curve is then used to determine the exact ion concentration of any sample that is placed in the sample receptacle.
