Linear Expansion Apparatus

Linear Expansion Apparatus The linear expansion Apparatus is designed to study the expansion of metals by applying heat to the metals. In the steam chamber, a metal rod is inserted to be applied with steam. The expansion takes place with instantly recognized by the indicator mounted on the end. A simple way to determine the coefficient of the linear expansion of metals. Used to determine the coefficient of expansion of different metals. The rod to be tested is placed inside a tube that has both an inlet and outlet for steam. A thermometer monitors temperature change. A bell or galvanometer is used to gauge the exact point of contact of the micrometer for precise measurement. Provided with 3 Rods--Iron, Copper and Brass.
