温度计 (3) - 玻璃

Set of 3 Vintage Galileo Galilei Glass Thermometers - 43cm and 2 × 34cm

一组3个复古加利略·伽利略玻璃温度计 - 43厘米和2个34厘米

A beautiful and captivating lot of three (3) classic Galileo Galilei thermometers made of high-quality blown glass.
一组美丽迷人的三件套，由高质量吹制玻璃制成，是经典的伽利略玻璃温度计。

Based on the physics principle discovered by Galileo Galilei, these decorative instruments measure room temperature through the buoyancy of precisely calibrated, colorful glass spheres.
基于伽利略发现的物理原理，这些装饰性仪器通过经过精确标定、色彩斑斓的玻璃球的浮力来测量室温。

As the ambient temperature shifts, the liquid inside the cylinders changes density, causing the spheres to rise or sink.
随着环境温度的变化，圆柱内的液体密度发生变化，导致玻璃球上升或下沉。

- 1x Large Thermometer: Height : 43 cm (features dark blue and green glass spheres)

Excellent condition. The glass bodies are perfectly intact with no cracks or deep scratches. All internal liquid spheres are completely sealed, correctly calibrated, and fully functional. The golden and silver-toned temperature tags are clean and clearly legible, currently indicating a consistent ambient temperature between 21°C and 22°C across all three pieces.
品相极好。玻璃主体完好无损，无裂纹或深划痕。所有内部液球均完全密封、标定正确、功能完好。金色和银色调的温度标签干净且字迹清晰，目前三件都显示一致的环境温度在21°C到22°C之间。

Due to the highly fragile nature of these glass instruments, this lot will be packed with professional care. Each thermometer will be individually secured in thick bubble wrap and housed in a sturdy, shock-absorbent box to ensure they arrive safely at their destination. Worldwide tracked shipping.
由于这些玻璃仪器极易损坏，本批次将采取专业包装。每支温度计将单独用厚泡沫纸包裹并置于结实、具抗震功能的盒中，确保安全抵达。全球可追踪运输。
