Air permeability is an overall measurement of process performance and structural uniformity of produced material. In some technical advanced materials, the permeability or breathability is the key property of the end use. Often these materials (separator films, membranes, breathable films etc…) are very low porous and thus out of the measurement range of common instrumentation. Furthermore, the measurement of low porous material can take very long using traditional instruments.
ACA Permi Lab LP 100 (5-2500 Gs) is designed for fast and easy air permeability measurement of low porous materials like battery separator films, medical grades and mebranes
ACA Permi Lab LP 500 (10 000 – 500 000 Gs) offers the widest measurement range available. The device is designed for the most dense materials such us water based barrier coated papers and board
