Sumario:[EN] The cultural heritage preservation brings together preventive conservation, remedial conservation and restoration. Most of these tasks are carried out in suitable workshops where cultural items are kept for variable periods of time. Since chemical reagents are used in such workshops for a wide variety of works, the air quality control is an important subject to guarantee the optimal conservation of the objects and to provide healthy working conditions, simultaneously. The assessment of the air pH is one of the most direct procedures to know the real degradation risk of cultural items. The chemical sensors patented by the research team CERVITRUM (Institute of History, CSIC) are able to qualitative and quantitatively evaluate the pH of the air. In the present research these sensors are used with the aim to evaluate the environmental conditions of a painting on canvas restoration workshop from the Fine Arts Faculty of the Complutense University (Madrid, Spain). The research scope highlights the importance of analyzing the interaction between the environment and the reagents, either individually or coordinately, and as a function of the spaces devoted to restoration tasks. After the synthesis, installation and recording of the sensors response, the results show that, under the normal use conditions and the climatic variations occurred during the evaluations carried out, the environmental quality of the workshop is suitable enough to guarantee the conservation of the paintings during the restoration process
