US-02 SEEBECK EFFECT

UTH-01A THERMAL EXPANSION USING MICHELSON
This device includes a Michelson interferometer and an oven,
together with a sensor and mirrors etc. Displacement of the
specimen ends are measured in terms of the number of
interference fringes. Therefore, the linear expansion coefficient of
the testing material can be calculated accurately.
He-Ne Laser: 1.0 mW@632.8 nm
Type of Sample: Copper, aluminum, and steel
Sample Length: 150 mm
Heating Range: 18 °C ~ 60 °C, with temperature-control function
Temperature Measurement Accuracy: 0.1 °C
Display Value Error: ± 1%
Power Consumption: 50 W

UTH-01 HEAT EXPANSION IN SOLIDS

If solid bodies are heated up, they generally expand to a greater or
lesser degree. In this experiment,
hot water is allowed to flow through tube with rod made of brass, steel
and glass. The expansion in their length is measured using a dial
gauge. The linear expansion coefficients for the three materials are
then calculated from the change in their length.
