Coefficient of Linear Expansion Apparatus (Horizontal Type) with Spherometer Brass, Iron & Nickel Rods

Product Description

This Coefficient of Linear Expansion Apparatus (Horizontal Type) is a precision laboratory setup used to determine the thermal expansion of solids, especially metals, with high accuracy. The apparatus includes a speedometer dial gauge for measuring minute elongation during heating and comes with three interchangeable metal rods “ Brass (Nickel-plated for corrosion resistance), Iron, and another standard rod “ each 50 cm long.

The setup features a long horizontal heating pipe, suitable for uniform steam or hot water distribution across the rod. It is ideal for use in physics and engineering laboratories to study the linear thermal expansion coefficient () of different materials.

This version comes with superior-quality components, including a nickel-plated brass pipe for improved durability, finish, and performance.
