After more design and upgrades, the second version Foam Porosity Tester F0023 was released in late 2001. Once again improving the accuracy of foam porosity testing. This model boasted variable flow ranges, allowing for more ranges of conditions of testing foam porosities. A huge feature of this model was the addition of an optional printer that allowed for data recording and printout, further increasing reliability and repeatability of tests. This model was truly the jump to digital, using differential pressure transducers instead of manometers, and digital flow sensors instead of analog meters.
