• Modern version of the popular heat conductometer • Convenient to use - no messy wax or match heads • Quick, visible, numerical results with lower temperatures needed - only hot w ater 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. Specifications Height: 20cm Width: 5.5cm Weight: 145g Bar dimensions (each bar): Length: 13.5cm Width: 0.9cm Thickness: 0.5cm Display temperature range: 35°C - 42°C x 1°C Show more
