Description Overview This machine is based on the ISO2439 testing method B, used to test the indentation of foam at 25% and at 65% with an indentation force of 40%. Indentation force ratio is also available. The sample is placed between the upper and lower plate; with a prescribed speed, the pressure plate presses down on the compression sample. When the top pressure plate is under stress, it changes the pressure into a voltage signal that is displayed on the screen.
