School Lab Linear Expansion Apparatus

School Lab Linear Expansion Apparatus

For comparative experiments of coefficients of linear
expansion. Heating extent(:simultaneously different metal rods (iron .brass and aluminum).
Equipped with a spirit lamp and reading connected pointer-needles on scale.
base:22x9cm, metal rod:(brass, copper, aluminium and iron) length: 18cm
The three wire expansion metal rod, diameter 6mm, length 180mm; rod end is round, the top screws can be inserted into the instrument left, the other end is a chute can be loaded into the pointer below; copper and iron, aluminum rods are respectively connected with red, blue, white Sanmei pointer pointer on a scale; in the 0 sign "who, when the metal rod under heat expansion, the pointer will be pushed away from the metal rod extension" 0 "bit line.
The floor is equipped with a disk for storing alcohol lamp. Also Linear Expansion Apparatus equipped with an aluminum cover, used to control the flame.
The overall size is about: 282*226*92mm.
