The first version of
IDM Instruments’ Foam Porosity Tester F0016 was designed and released in
the 1980s, in accordance with global industry standards, and was used to
determine the ease with which air passed through a cellular structure, namely
foam, by comparing the relationship between pressure and flow when subjected to
different foam samples. It used vacuum chambers with manometers and was
controllable via a manual dial to fine tune flow. This version was purely
analogue and required fine use of the dial and flow tubes to be able to give
accurate test results. Due to the purely analog design, it was difficult to
achieve accurate yet repeatable test results.
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.
IDM Instruments’ constant search for increased quality and
consistency through quality control and improvement has perfected our designs,
leading to our current version in 2013’s Foam Porosity Tester F0031.
Introducing a bright and easy-to-see touchscreen, a 30% smaller footprint
compared to previous versions, much faster automatic results, digital manometer
with a 0-500 Pa ± 1% range, variable pressure ranges, different flow range
options (0.2-20L/min, 2-200L/min, 5-500L/min), automatic pressure control and
RS232 data output. Not only does this version handle regular foams and
flexible cellular polyutherane, but also Visco foams (memory foam). Once the
pressure has been digitally set on the display, and once the foam porosity
tester reaches the set pressure, the rate of airflow is automatically locked in
and held on the flow display, automatically completing the test in seconds.
Never has it been so easy to test the porosity of foam.
