A thermoscope is an early device used to measure temperature changes, typically consisting of a sealed glass tube with a bulb at one end filled with liquid. As temperature changes, the liquid expands or contracts, providing a visual indication of temperature variations. It is considered a precursor to modern thermometers, as it lacked a standardized scale for precise measurement. The concept of the thermoscope laid the groundwork for the development of more accurate thermometric instruments.
