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.
