Linear Expansion Model About

Linear Expansion Model

We are a leading manufacturer, supplier, and exporter of Linear Expansion Models designed for physics laboratories, science classrooms, STEM education, and thermal expansion demonstrations. This educational apparatus helps students understand the concept of linear expansion of solids due to temperature changes in a simple and visual manner.

The Linear Expansion Model consists of a metal wire stretched between two support pillars mounted on a sturdy base. A weighted indicator is suspended at the center of the wire. When the wire is heated, it expands in length, causing a noticeable change in the position of the suspended weight. This demonstration clearly illustrates how materials expand when subjected to heat.

The model is widely used in schools, colleges, and science laboratories for practical demonstrations of thermal expansion principles.

Accurate Linear Expansion Measurement

Designed for educational settings, this model provides consistent and precise measurement of linear expansion in solids. Its high-resolution analog dial gauge ensures students can observe changes as minimal as 0.01 mm, offering an engaging way to understand thermal expansion concepts.


Robust and User-Friendly Design

The apparatus consists of premium materials, including metal rods and a durable wooden base. Minimal and tool-less assembly allows educators and students to set up experiments quickly. Export-quality packaging ensures safe transit and longevity in labs.


Ideal for Group Learning

With a capacity for 2 to 6 students per set, this linear expansion model facilitates collaborative experiments. It is suitable for school and college physics laboratories, aligning with standard educational curricula.
