More about this item

This nautical version of the Tendency Barometer consists of two liquid filled tubes.The unique horizontal U-shaped barometer tube is open-ended and is filled with a red fluid.The closed thermometer tube is filled with blue methyl alcohol. Since both tubes are exposed to the same temperature, the only thing making the fluid levels different is the atmospheric pressure on the open-ended barometer tube. When the fluid levels are the same, the weather is changing.When theredfluid level is to the left ofbluefluid level, the weather is fair (high pressure pushes the red fluid down in the tube).When theredfluid level is to the right of theblue, stormy weather is predicted (low pressure allows the red fluid to move up the tube).Actual pressure readings in inches and millibars (hPa) can be taken and a weather forecast made by using the tendency slider parallel to and above the measuring tubes. The Adie Tendency Barometer, known as the Ships Hull Tendency Barometer, is mounted on a sandblasted frosted glass frame.A sailing ships half hull, made of solid wood, is mounted below the measuring tubes to give the instrument a definite nautical flair.This unit measures 15 inches wide by 9 inches high and weighs about 3 pounds.Appropriate for home, boat or office and makes a unique corporate gift.Comes fully assembled and with a calibration kit for setting to local altitude. Made in Belgium.
