Product Description

The Smoke Density Tester for Building Materials is designed to measure the smoke generation characteristics of construction materials under controlled combustion conditions. It evaluates the optical smoke density produced when materials are exposed to heat or flame, helping determine fire safety performance and compliance with international standards.

This testing equipment is widely used in fire testing laboratories, building material manufacturers, quality inspection agencies, and research institutions.

Testing Principle

The instrument measures the reduction of light transmission caused by smoke generated during material combustion. The optical system records changes in light intensity, allowing accurate calculation of smoke density values.

The test results reflect how much smoke a material produces in a fire scenario, which is critical for building safety evaluation.
