Thermal Conductivity Bars

Catalogue No: 1060390

Ideal for comparison of thermal conductivity of different metals quickly and conveniently. Features liquid crystal indicators mounted in robust holders. Four identical metal bars of same shape and size, each of different metal: copper, aluminumm, brass and steel held firmly in a rigid moulded plastic carrier with a hole for convenient suspension. Thermal conductivity value of each bar is clearly marked. The sensitive liquid crystal temperature indicators working in low temperature range are attached to each of the four metal bars and are marked at 1cm interval to facilitate charting the movement of temperature gradient. The rate of heat flow is indicated by timing the colour change across these markers. The demonstration requires only a container of hot water, thus doing away with open flames, hotplates, or messy melting wax method of comparison with result in a very short time. Timing the heat pulses enables estimation of the relative conductivities.
