Gurley 4340 Automatic Densometer & Smoothness Tester

Densometers are the accepted instruments for measuring porosity, air-permeability or air resistance of sheet-like materials.

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.
