Maximum Inc. Proteus Barometer

Proteus is a true scientific-grade instrument if you are looking to take weather tracking and observing to the next level. It is our highest quality, temperature compensated, aneroid barometer.

The French gauge movement is temperature compensated to -10 degrees F/-23 degrees C, with a standard deviation of ±0.08″ Hg. The dial window cutaway provides visibility of the full-sized barometer movement, while an optional fabric encasement protects it from dust and scratches.

Because of its superior quality and craftsmanship, you will be proud to display this instrument in your home or office. It is also an excellent addition to any classroom or lab.

Proven by generations of sailors for over 200 years, the barometer remains an accurate weather forecaster. The direction, speed and duration of pressure changes tell you what the weather will do next. The drops and rises of a barometer reveal what's happening far upwind and downwind of your location.
