Thermal Conductivity Bars

Easily compare the thermal conductivity of four different metals—steel, brass, aluminium, and copper—in a single, hands-on experiment. This compact, classroom-friendly unit allows students to observe heat transfer in real time.

Each metal strip is securely mounted to a colour-changing strip thermometer and affixed to a sturdy plastic base. Simply immerse the metal ends into a beaker or glass of hot water, and watch the thermometer visually display the rate of heat conduction through each metal.
