The Model 4340 AutomaticDensometer & Smoothness Tester measuresthe porosity, air-permeability or airresistance of sheet-like materials. Itcombines the abilities of a low, standardand high pressure tester with a digitaltimer that provides a reading in seconds.
An auto-drive mechanism, enables youto program the number of tests as wellas the span they are tested over.Therefore, a sheet or strip of paper can beanalyzed automatically.
Applications
Porosity and smoothness of paper, textiles,paperboard, films, membranes, filtermedia, packaging, perforated metals andothers.
Quality control — Air permeability can bea direct representation of the uniformity ofmaterial.
Analyze effects of treatments such ascoatings, sizing agents, inks, resins orother additives.
