Ideal apparatus for the comparison of the thermal conductivity of different metals quickly and conveniently.
· Features convenient liquid crystal indicators mounted in robust holders that show how a red zone of 40⁰C moves up the bars
· Comprises of four metal bars of the same shape & size
· The tip of the heated bars are immersed into cold water to show how conductivity applies to heat leaving the metal
· The tops of the bars are designed to be touched with a fingertip to reinforce the colour observations of the bars
