Porosity sensor

For Air Permeability Analysis

Key Features

Contact, one sided online measurement
Positive Air Flow method, for high permeability materials
Unique and tailored head designs
Tolerates sheet fluctuations
Correlates well with Gurley, Bendtsen, Coresta etc.
Fast measurement suitable for scanning profile measurement

Measuring Method

The Scienta Porosity Sensor measures the air flow through the web while maintaining constant air pressure. The Sensor head is in constant contact with the sheet. High porous / permeable materials are measured using positive air flow pressure. Scienta Porosity sensor is not available for dense / low permeability materials.

Benefits

To process applications such as filter paper, board, nonwovens, plastics, glass fiber etc.
