Non invasive measurements with portable devices are becoming the general trend for the development of instruments dedicated to the study of heritage objects. Two instruments are described in this paper, based on two distinct surface features that are colour and texture, using particular set-ups adapted to our needs: a spectro colorimeter operating in backscattering mode and a roughness-meter using a field extension obtained by stretching the axial chromatism dioptric. Examples of application illustrate their use. It is obvious that this kind of investigation can only be carried out in an interdisciplinary context where art historian, conservation scientist, conservator and photographer share their knowledge and their skill.
