Schatz Barometer Instructions

Barometer History
••• Brian Snelson/

Schatz barometers are used to determine the air pressure, whether you are out sailing or simply walking around your house. The typical Schatz is an aneroid model, meaning it uses a bellows and spring to function, rather than a mercury tube like other barometers. As the weather changes -- such as from sunny, clear skies to drizzling rain -- the Schatz will note the changes. Know how to read the Schatz and record its information as the weather takes a turn for the better or worse.

    Choose a wall or other surface around your house or boat to mount the Schatz onto.

    Gently hammer the hooks into the surface over the two middle loops of the barometer to mount.

    Tap the metal frame of the barometer gently to get a reading; the barometer's pressure needle will move to the right if the weather is drying out, it will move to the left if it is either raining or about to rain and it will not move if the weather is holding steady.

    Write down the reading you get on the barometer with the pencil and paper; for example, if the reading is "760 mm" and "Change," then write down "760 mm Change." Note the needle with no end is the one that reads the pressure, while the one with the curved end reads temperature.

    Check the barometer periodically and write down the reading the pressure needle gives with pencil and paper. Compare the readings you've written down over time to track weather.

    Things You'll Need

    • Wall or other mounting surface
    • Hooks
    • Hammer
    • Pencil
    • Paper


    • Adjust the barometer by pulling out the hooks with pliers and flipping it over. Turn the small screw in the back with a flathead screwdriver clockwise to move the pressure readings to the right, and turn it counterclockwise to move readings towards the left. Remount the barometer with the hooks and hammer to the surface when finished.
