The Galileo Weather Station

No Longer Available

This Galileo thermometer combines art with science. It provides an accurate reading of current weather conditions. Temperature is indicated by the lowest "floating" sphere in the top grouping. As accurate as laboratory thermometers. Predict changes in the weather by referencing fluid rise and fall in the barometric tube. The hygrometer measures humidity.

How the thermometer works:

The colored floating spheres are "pushed" either up or down depending on the changing density of the clear fluid inside the glass thermometer body. When the temperature goes up, the clear fluid becomes less dense and rises - forcing the spheres down one by one. When the temperature goes down, the clear fluid becomes denser - forcing the spheres upward.

How the barometer works:

While not as accurate as modern day aneroid barometers, the principle of the early "Water Barometer" is sound. When atmospheric pressure decreases, the fluid is pulled upward toward the top of the barometer tube (low pressure). As atmospheric pressure increases, the fluid is "pushed down" (high pressure). Standard atmospheric pressure at sea level is 29.92".

How the hygrometer works:

The Hygrometer Gauge measures % of relative humidity in the air. Humidity is determined by reading the number at the end of the indicator pointer.

Please note that we DO NOT accept returns of Galileo Thermometers/Galileo Weather Stations due to the chance of breakage during shipment. Galileo's that have been repacked often do not survive a second shipping. For that reason, we do not accept returns on this item.

HISTORY

This fascinating weather instrument provides a reading of the current weather conditions using several scientific methods established hundreds of years ago.

The Thermometer portion of the instrument works on a "Natural Law of Physics" discovered by Galileo Galilei (1564-1642).   It was Galileo, "the Father of Modern Physics", who established the principle that the density of liquid changes with temperature.  Our thermometer is a replica based on Galileo's experiments.  When the temperature rises, the liquid in the glass cylinder becomes less dense and the spheres sink slowly, one by one.   Conversely, the spheres will rise as the temperature decreases.

The lowest floating sphere in the upper portion of the cylinder indicates the correct temperature.

The side mounted "Barometer Tube" or "Water Barometer" dates back to early 17th century Europe.  A time when farmers and mariners relied on instruments such as this to predict changes in the weather.   The rise and fall of the fluid in the vertical tube indicates a change in barometric pressure and coming weather conditions.  If the fluid rises, there is a chance of bad weather.  Falling fluid indicates chance of fair weather.

The Hygrometer measures relative humidity using a material that changes shape and length when it gains or loses moisture. The material is connected to a rack and pinion gear system which drives the pointer needle to give the reading.

PRECAUTIONS FOR GALILEO THERMOMETERS

The liquid in the Galileo Thermometer cylinders is completely sealed and can be safely displayed in your home. By following a few basic guidelines, you can enjoy this product for a lifetime. Keep out of reach of small children and pets. Place on level surface where accidental tipping cannot occur. Keep away from sources of heat such as, fireplaces, stoves and radiators. Do not store in your automobile trunk. Keep out of direct sunlight. This product contains paraffin, petroleum distillates, which are found in many household products. The same safety precautions apply.

Should breakage occur, keep away from open flames. Fluid in this product is combustible. Be careful when picking up glass pieces or fragments, they may be sharp. Open all windows to increase ventilation and wipe up excess with damp cloth. Rinse remaining residue from cloth and allow to dry outdoors.

Thoroughly wash hands with soap and water.

If eye contact occurs, flush eye with water for a least five minutes and contact physician.

Do not take internally.

Harmful or fatal if swallowed.  If swallowed, DO NOT INDUCE VOMITING. ASPIRATION HAZARD.  Immediately call physician or Poison Control Center at 1-800-876-4766.  Reference the following product identifiers # CAS 64742-48-9 and # CAS 00112-34-5.
