A method for compensating for a temperature-related error in an electrochemical sensor without using separate sources of temperature measurement by measuring sensor current, temporarily lowering sensor voltage to a first level below a reaction-sustaining threshold, measuring a first offset current, adjusting sensor voltage to a second level below the threshold, measuring a second offset current, calculating a difference between the offset currents, deriving a temperature compensation value from the difference based on empirical data, and adding the value to the measured sensor current. A computer system may execute the method as an algorithm stored in memory, provide automatic control of the sensor, and provide continuous display of corrected output values.

L'invention porte sur un procédé de compensation d'une erreur liée à la température dans un capteur électrochimique sans utiliser de sources séparées de mesure de température par mesure d'un courant de capteur, abaissement temporaire d'une tension de capteur à un premier niveau inférieur à un seuil d'entretien de réaction, mesure d'un premier courant de décalage, ajustement de la tension de capteur à un second niveau inférieur au seuil, mesure d'un second courant de décalage, calcul d'une différence entre les courants de décalage, déduction d'une valeur de compensation de température à partir de la différence sur la base de données empiriques, et addition de la valeur au courant de capteur mesuré. Un système informatique peut exécuter le procédé en tant qu'algorithme stocké dans une mémoire, fournir une commande automatique du capteur, et fournir un affichage continu de valeurs de sortie corrigées.
