The Auto FPT is used for monitoring the porosity of flexible cellular polyurethane. 

The machine determines how easy air passes through a cellular structure.  Airflow values may be used as an indirect measurement of certain cell structure characteristics. The F0031 model foam porosity tester is made with reference to international standards for measurement of a flexible cellular test piece, 50mm x 50mm x 25mm, it is placed in a vacuum chamber cavity and a specified automatic constant differential air pressure is applied. The F0031’s Pa Pressure can be digitally set on the display and once the FPT reaches the Pa automatically the rate of airflow at the set Pa is locked in and (Held) on the Flow display automatically completing a test in seconds.
