The invention describes a sensitive measuring probe and an associated measuring procedure for the detection of agents and their concentration in gases and/or liquids and this measuring probe can be used under the most varied real measuring conditions without additional expenditure and does not require a heating element. According to the invention, this requirement is fulfilled in that a covering film consisting of a liquid is located above the sensor-active layer of a measuring probe and the covering film is included in the active zone of the measuring probe and the combination of various partial conductances, in particular, of the substance, the covering film and the active surface formed between both of these is included in the determination of the total conductance without compensation.
L'invention concerne une sonde de mesure (1) sensible et un procédé de mesure associé pour la détection d'agents et de leur concentration dans des gaz et/ou des liquides, ladite sonde s'utilisant de manière simple dans les conditions de mesure réelles les plus diverses et ne nécessitant aucun élément chauffant. A cet effet, un film de recouvrement (7) constitué d'un liquide se trouve au-dessus de la couche détectrice d'une sonde de mesure (1). Ce film est intégré dans la zone active de la sonde de mesure (1), et la combinaison des différentes conductances partielles, notamment de la substance (4), du film de recouvrement (7) et de la surface (8) active se formant entre les deux, est utilisée pour déterminer la conductance globale sans compensation.
