The Blaine Air Permeability Apparatus is designed to meet rigorous standards for determining the fineness of cement, pozzolanas, and similar powdery materials by measuring the specific surface area. Manufactured to comply precise and reliable results, crucial for laboratory and quality control applications in construction and materials testing industries.

This apparatus is essential for assessing the performance of powdered materials, which can significantly affect the strength, durability, and hydration of cementitious products. It includes a complete set of high-quality, precision components tailored for accurate air permeability testing.

• Compliance: Meets IS:4031 (Part 2), IS 5516, ASTM C204, and EN 196-6 standards, ensuring results meet both Indian and International quality norms.
• High Precision: The apparatus includes components such as a brass permeability cell and an electronic balance, enhancing accuracy in specific surface measurement.
• Durability and Stability: Made with robust materials, including a wooden stand and brass cell, for long-term stability in laboratory environments.
