Dual Weather Station a traditional way to read the temperature and predict the weather. Two historical devices in one.
Assembled size: 17.5 x 14 x 7cm Storm glass.
Once used by seafarers to predict oncoming storms, the storm glass barometer came into general use in the early 1700s, and responds to atmospheric fluctuations to forecast the weather.
Admiral Robert Fitzroy conducted a detailed study of this instrument between 1834 and 1836.
He refined the chemical formulation and published observational guidelines on how to predict the weather, see instructions inside.
Galileo Thermometer In 1593, Galileo Galilei discovered that the density of liquids reacts predictably to changes in temperature.
He invented a device that allowed temperature variations to be measured.
HOW IT WORKS The sealed glass cylinder contains five floating glass bulbs. Each bulb has a calibrated, weighted metal tag. The temperature is determined by the lowest floating bulb.
When there is a bulb in the middle, the temperature should be read as between this degree and the lowest floating bulb. Temperature range: 16-32 C.
