The thermoscope didn't measure temperature differences

A thermometer is a device that measures temperature and provides a numerical value, while a thermoscope is a simple temperature-sensing instrument that shows changes in temperature without providing specific values. Thermometers are more accurate and calibrated, while thermoscopes are more qualitative in nature.
A thermoscope is an early instrument to detect temperature changes without displaying specific temperatures, while a thermometer is a more advanced device that can measure and display temperature readings with numerical values. Thermoscopes typically use properties like thermal expansion, while thermometers use a standardized scale such as Celsius or Fahrenheit for measurement.
Galileo developed the thermoscope, the first instrument to measure temperature qualitatively. It was Sanctorius Sanctorius who devised and added the scale to the thermoscope to measure the temperature quantitatively and since then has been called the thermometer.
A thermoscope is an early instrument used to detect temperature changes by observing the expansion or contraction of a liquid (such as water or alcohol) in a sealed tube. It is considered a precursor to the modern thermometer, which provides more accurate temperature readings using a standardized scale.
Galileo Galilei invented the first device that measured temperature in the early 16th century, known as the thermoscope. It was a forerunner to the modern thermometer, which was further developed by scientists like Daniel Gabriel Fahrenheit and Anders Celsius.
In 1612 the inventor Santorio Santorio became the first to put a scale on his thermometer. It was perhaps the first crude clinical thermometer as it was designed to be placed in a patients mouth for temperature taking
