- Model 1900N is designed to test such cushion materials as urethane foam, sofa and sheet.
When necessary test conditions (preloading force, preloading time, etc.) are input in accordance with the procedures shown on the screen,this tester measures the initial thickness and calculates a load value from the set compression ratio or a compression ratio from the set load value to acquire data at three freely set points of thickness.
