SP Bel-Art, H-B DURAC Glass Weather Ball Barometer; 152mm Diameter
Indicates changes in air pressure quickly and accurately.
Once filled the air trapped inside the ball is no longer subject to variations in atmospheric pressure
Liquid in the indicator tube is directly affected by atmospheric pressure
When pressure rises, liquid in the indicator tube is pushed down; improvement in the weather can be anticipated
When pressure falls, liquid in the indicator tube rises; deterioration in weather can be expected
