Description
- Densometers are the accepted instruments for measuring porosity, air-permeability or air resistance of sheet-like materials.
- The 4340 combines the ability of a low, standard and high pressure densometer and smoothness tester and provides a reading in seconds.
- An auto-drive mechanism enables the user to program the number of tests and the span they are tested over.
The Model 4340 Automatic Densometer & Smoothness Tester measures the porosity, air-permeability or air resistance of sheet-like materials. It combines the abilities of a low, standard and high pressure tester with a digital timer that provides a reading in seconds.
An auto-drive mechanism, enables you to program the number of tests as well as the span they are tested over. Therefore, a sheet or strip of paper can be analyzed automatically.
Applications
- Porosity and smoothness of paper, textiles, paperboard, films, membranes, filter media, packaging, perforated metals and others.
- Quality control – Air permeability can be a direct representation of the uniformity of material.
- Analyze effects of treatments such as coatings, sizing agents, inks, resins or other additives.
