Ambient Weather WS-YG709 Galileo Thermometer, Barometer, Hygrometer and Quartz Clock Weather Station (Silver) Feature

• 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 one would expect with a fine, handcrafted weather instrument from Ambient Weather.
• Includes Ambient Weather one year warranty.
• The Galileo thermometer consists of a sealed glass tube that is filled with water 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. So, after the weighted tags are attached to the bubbles, each differs very slightly in density (the ratio of mass to volume) from the other bubbles, and the density of all of them is very close to the density of the surrounding water.
• As the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles. As the temperature of the water changes, it either expands or contracts, thereby changing its density. So, at any given density, some of the bubbles will float and others will sink. The bubble that sinks the most indicates the approximate current temperature. The rich, solid wood framed cherry weather station with lacquer finish measures barometric pressure (in mbar and inHg) and humidity (%). The barometer allows for sea-level calibration up to 3,000 feet.
