Macroday - Measuring device

This weeks theme on Macroday is Measuring device, such as rulers, tapemeasures,scales etc.
Ypu probably wonder what my photo has to do with measuring devices, but I can tell you it`s a photo of a Galileo thermometer....I don`t usually use the texturizer in PS, but on this photo I think it looks ok ;-} Hopefully I am not totally of theme here.......
