Glass Galileo thermometer, 42 cm tall, with 7 coloured bulbs measuring temperatures from 18 to 24°C. This version stands out due to its clear colour differentiation and precise 1-degree calibration.

↕ 42 cm Ø 5 cm


This 42 cm multicolour Galileo thermometer is one of the most balanced models in terms of size, readability and measurement precision. The seven coloured bulbs each represent a specific temperature, allowing for accurate readings in single-degree increments between 18 and 24°C. The variation in colours ensures that each temperature step is immediately distinguishable, while the movement of the bulbs provides a visual indication of even subtle changes in room temperature. Its proportions are carefully considered, offering a stable and clearly visible display without appearing oversized.

The cylindrical body is made from high-quality, thick clear glass that maintains transparency over time and ensures structural stability. Each bulb is precisely calibrated based on density and fitted with a metal temperature tag for accurate reading. This thermometer is manufactured in Germany, where strict quality control guarantees long-term reliability. Its classic design and balanced dimensions make it suitable for placement on a sideboard, desk or windowsill where both function and presentation matter.

About the Galileo thermometer

The Galileo thermometer is based on a principle discovered by Galileo Galilei in the early 17th century: the density of liquids changes with temperature. Each coloured glass bead has been carefully weighted so that it rises or sinks to indicate the current ambient temperature.

Key features

Multicoloured glass beads

  • Brightly coloured beads in various shades for an eye-catching display
  • Easy-to-read metal labels indicating the temperature in °C

High-quality construction

  • 42 cm tall, hand-blown borosilicate glass cylinder
  • Stainless steel stopper for a secure, leak-proof seal
  • Stable metal base to prevent tipping

How it works

When the room temperature changes, the density of the surrounding liquid adjusts. Each coloured sphere has a specific density and will float or sink until it reaches its ‘neutral buoyancy’. The lowest-floating sphere in the top group indicates the current temperature.
