Thermal Conductivity Bars quickly show heat transfer rates.

  • This simple and ingenious device quickly and graphically shows students how different metals conduct heat at different rates.
  • It consists of four identically sized bars of common metals - steel, brass, aluminum, and copper - mounted parallel to one another in a plastic support.
  • Attached to each bar is a liquid crystal thermometer.
  • When the ends of the bars are immersed in hot water, the thermometers quickly show the progress of heat along each bar.
  • Students can measure the time for the tops of the bars to reach the top display temperature (42°C) and discover how well each metal conducts heat.
  • Height: 20 cm, Width: 5.5 cm, Weight: 145 g.
  • Bar dimensions (each bar): Length: 13.5 cm, Width: 0.9 cm, Thickness: 0.5 cm.
  • Display temperature range: 35°C - 42°C x 1°C.
