Description

The BESMAK Electronic Blaine Air Permeability Apparatus is designed to determine the fineness of Portland cement by measuring its specific surface area, expressed as the total surface area in square centimeters per gram of cement.

For optimum accuracy, testing should be performed in a temperature-controlled laboratory environment. Compared with manual Blaine apparatus, the electronic model provides greater precision and repeatability by utilizing an automatic vacuum pump and an electronic timer to accurately measure the air permeability test duration.

Calibration is carried out using certified cement reference materials, such as NIST 114q, ensuring reliable and consistent test results.
