The Precision Linear Expansion Apparatus produces accurate determinations of the coefficient of expansion.

This precision apparatus will produce accurate determinations of the coefficient of expansion. Readings are repeatable to 0.005 mm.

This rigidly constructed apparatus requires no electrical accessories. Expansion rods can be easily replaced without removing stoppers by simply sliding one rod into the heating jacket that automatically ejects the other rod.

We offer four different expansion rods: aluminum, brass, copper and steel. Rods measure 60 cm long x 6.4 mm ( 1/4") in diameter.
