Quick Answer: The Thermoscope is a physics apparatus that shows changes in temperature through the expansion and contraction of its contents, seen as movement in a tube. It gives a qualitative indication rather than an exact temperature reading.

About This Product
The thermoscope is the idea behind the thermometer: warming the apparatus makes the level move one way, cooling moves it back. Teachers use it to compare temperatures, explain thermal expansion and heat transfer, and show why a thermometer needs a scale to give actual values. The Thermoscope can be supplied on export terms to Japan, Estonia, Tanzania, Luxembourg and Jordan.
Frequently Asked Questions
How is a thermoscope different from a thermometer?
A thermoscope shows that temperature is changing but is not calibrated, so it does not give an exact temperature as a thermometer does.
