Densometers
Model No. :
Brand : Gurley
Gurley Densometers are the industry standard for evaluating the porosity and air resistance of flat materials like papers, plastics, and membranes. They measure the exact time needed for a specific air volume (25cc to 400cc) to flow through a standard test area under uniform pressure.
- Low, standard, and high-pressure configurations
- Manual and automatic testing units available
- Compliant with TAPPI, ASTM, and ISO standards
