Air Permeability Tester

About Air Permeability Tester

The Air Permeability Tester is a precision laboratory instrument used for determining the fineness of cement by measuring the specific surface area of cement particles. It is widely used in cement testing laboratories and quality control departments to ensure consistent cement performance in construction applications.

This apparatus works on the principle of measuring the resistance of air passing through a compacted bed of cement. The rate of airflow is used to calculate the fineness value, which directly influences the strength, setting time, and workability of cement.

Manufactured with high-quality components and a robust design, the Air Permeability Tester ensures accurate, repeatable, and reliable test results. It is suitable for routine laboratory testing as well as advanced research applications.

Key Features:

• High-accuracy measurement of cement fineness
• Based on air permeability (Blaine principle) method
