Lyssy Tester Works In Controlled Environment
Glen Rock, N.J.-based PBI-Dansensor America Inc. reports its Lyssy Water Vapor Permeability Tester
reduces from days to minutes the time required to test moisture barrier properties of nonwoven
materials and finished products.
The Lyssy tester works within a sealed chamber under controlled humidity and temperature, whereas traditional cup test methods must reckon with changing conditions caused by ambient moisture and temperature. It is programmed to handle multiple, reproducible readings within a designated time frame and eliminates the possibility of human error.
