DEVICES, SYSTEMS AND METHODS FOR TESTING GAS SENSORS AND CORRECTING GAS SENSOR OUTPUT

摘要

A method of adjusting the output of an electrochemical sensor includes the steps of: simulating the presence of an analyte gas electronically; measurin g a response of the sensor to the electronic simulation; and adjusting the output of the sensor as a function of the measured response to the electroni c simulation. The method of adjusting the output of an electrochemical sensor having a working electrode and a counter electrode preferably includes the steps of: electronically causing a current flow between the working electrod e and the counter electrode; measuring a response of the sensor to the current demand; and using the measured response to adjust the sensor output during sampling of an analyte gas.
