The Precision Linear Expansion Apparatus produces accurate determinations of the coefficient of expansion.

Bimetallic strips attached to wooden handle to study thermal energy.

Bring Some Heat Into the Classroom

This working model thermostat will demonstrate how differential expansion is used to control temperature. A bimetallic strip is used to open or close an electric circuit when temperature changes. The contacts will carry about three amperes. The unit can be operated with a 6 V lantern battery, low voltage power supply, or a blow dryer. Mounted on a metal base; approximately 15 cm high.

For demonstrating the differential expansion of two metals as shown by the curvature produced when the bar is heated. Each metal band is 200 x 15mm and riveted together.

Brass ball mounted on brass rod for thermal expansion experiments.

Conductometer with variety of metals to demonstrate heat conductance by various metals.

Demonstrate the Difference Between the Specific Heat of Objects.

Radiometer with four lightweight metal arms.

High quality linear expansion apparatus to study thermal expansion.
