This traditional weather station is both a work of art and an instrument at home in any fine study, library, office or upscale restaurant. * The rich, wood framed classic weather station measures temperature (galileo), barometric pressure (in and mbar), humidity (%) with analog clock. The antique weather station displays an air of quality and accuracy. * The Galileo thermometer consists of a sealed glass tube that is filled with liquid and several floating bubbles. The bubbles are glass spheres filled with a colored liquid mixture. * Attached to each bubble is a little metal tag that indicates a temperature. These metal tags are calibrated counterweights. The weight of each tag is slightly different from the others. * Since the bubbles are all hand-blown glass, they aren"t exactly the same size and shape. The bubbles are calibrated by adding a certain amount of fluid to them so that they have the exact same density. * Attached to each bubble is a little metal tag that indicates a temperature.
