Ambient Weather WS-YG720 Thermometer, Liquid Barometer, Hygrometer and Clock Weather Station 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, barometric pressure (liquid), 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.
  • The concept that 'decreasing atmospheric pressure predicts stormy weather' was postulated by Lucien Vidie -- and it's the basis for a weather prediction device called a storm glass or liquid barometer. It consists of a glass container with a sealed body, half filled with water.
  • A narrow spout connects to the body below the water level and rises above the water level, where it is open to the atmosphere. When the air pressure is lower than it was at the time the body was sealed, the water level in the spout will rise above the water level in the body and when the air pressure is higher, the water level in the spout will drop below the water level in the body.

Weather Ball Liquid Barometer - Sper Scientific (Model 739750)

Weather Ball Liquid Barometer - Sper Scientific (Model 739750) Reviews

Weather Ball Liquid Barometer - Sper Scientific (Model 739750) Feature

  • Height: 7.5"
  • Diameter: 4"
  • 90 Day Warranty
Torricelli (1608 - 1647) proved that air pressure was subject to variations and in 1643 he devised the first barometer. Goethe, the famous German playwright, who enjoyed scientific experiments, later developed his own simple, but effective barometer using the principles established by Torricelli. This barometer is based on Goethe's design. The Weathe Ball Barometer will indicate changes in air pressure quickly and accurately. The ball is filled with colored distilled water. Once filled the air trapped inside the ball is no longer subject to variations in atmospheric pressure. The liquid in the indicator tube, however, remains open to the atmosphere and is directly affected by atmospheric pressure. When atmospheric pressure rises the liquid in the indicator tube is pushed down and an improvement in the weather can be anticipated. When air pressure falls the greater pressure inside the weather ball causes the liquid in the indicator tube to rise indicating that a deterioration in weather can be expected. Comes with full instructions.
