Galileo Thermometer - Nauticalia - 130683

It works based on Galileo's principle of buoyancy and density. As the ambient temperature changes, the density of the liquid inside the tube changes. The glass globes, each with a different weight, rise or fall according to these density shifts, indicating the current temperature.

The specific temperature range is indicated by the engraved brass tags on the glass globes. Typically, these Galileo thermometers cover a range around room temperature, for example, from 16°C to 26°C (or similar variations depending on the specific model).

Galileo thermometers are decorative and educational tools that provide a general indication of room temperature. For highly precise scientific measurements, a digital or mercury thermometer might be preferred. This thermometer is most accurate in stable environmental conditions.

No, this thermometer is designed for indoor use only. Exposure to outdoor elements, direct sunlight, and extreme temperature variations can affect its accuracy and potentially damage the unit.

Identify the lowest-hanging glass globe in the tube. The temperature tag attached to this globe indicates the current ambient temperature.

Ensure the thermometer is on a level surface and has had time to acclimate to the room temperature (at least 30 minutes). If the temperature is stable, the globes will remain relatively still.

Please refer to the product packaging or the manufacturer's official website for specific warranty information, as this can vary.

The ambient temperature is likely higher than the highest temperature indicated on the globes. Allow the thermometer to cool or move it to a cooler location.

The ambient temperature is likely lower than the lowest temperature indicated on the globes. Allow the thermometer to warm up or move it to a warmer location.

This can sometimes occur due to temperature fluctuations during shipping or storage. Gently turn the thermometer upside down and back upright a few times to redistribute the liquid. If the issue persists, contact customer support.

Ensure the thermometer is on a perfectly level surface. Slight tilting can affect the buoyancy. Gently tap the base to allow globes to settle.
