In order to study the influence of several atmospheric parameters on Figaro type gas sensors response, we have designed a test equipment which allows us to characterize these kind of sensors under conditions of closely controlled temperature, humidity and contaminant gas concentrations. This equipment is mainly composed of a gas humidification system to satisfy the humidity and temperature control conditions, and a test chamber which enclose the sensors to be characterized. At first, this paper presents the developed system and its main requirements. Then, preliminary results are presented, showing the influence of the relative humidity on the behavior of an array of these sensors.
