Precision Linear Expansion Apparatus

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

For Measuring Thermal Expansion of Metals
Choice of Four Kinds of Rods: Aluminum, Steel, Copper, and Brass
No Electrical Accessories Available
Readings Are Repeatable to 0.005 mm
Easy-To-Replace Expansion Rods

This rigidly constructed apparatus requires no electrical accessories, and readings are repeatable to 0.005 mm. Expansion rods can be easily replaced without removing stoppers by sliding one rod into the heating jacket that automatically ejects the other rod.

Four expansion rods are available: aluminum, brass, copper, and steel. Rods measure 60 cm x 6.4 mm (1/4") in diameter. A steam generator is required.
