Barometric Pressure Instruments

Barometric Pressure Instruments are great for giving you a sneak peak at what the weather will be like tomorrow.  A barometer whose needle is moving clockwise, indicates improving weather and a barometer whose needle is moving counter-clockwise, indicates declining weather.  Barometers have also been know to provide early indications of aches and pains due to "that old football injury".  Maximum offers a full line of both aneroid and digital barometers which, like all of our weather instruments are made in the U.S.A. and backed by a 5-Year Limited Warranty.
