Mariners and landlubbers will both enjoy the local weather premonitions they receive from a Patriot Deck Barometer. What does a barometer measure? By tracking changes in atmospheric pressure, it will inform you of the short-term weather outlook. A double bellows holosteric movement tracks the changes in inches/Hg and millibars, which can be seen on the brilliant white dial. There are also five general forecasts – Stormy, Rain, Change, Fair and Very Dry – based on common pressure levels.

These handcrafted wall barometers for sale are based on Chelsea Clock’s well-known WWII engine clock. A black phenolic resin case resists heat, moisture and impacts for serious seafarers. The barometer is calibrated for sea level but can be adjusted for an altitude of up to 3,000 feet using the included mini screwdriver. We can adjust it for even higher altitudes at our Chelsea, Massachusetts factory. By adding the Patriot Deck Clock and Patriot Tide Instrument, you can form a weather station in a home, office or captain’s quarters.
