Materials Inc. (PMI), Ithaca, N.Y., has designed its new QS201A Integrity Analyzer to enable quick
and simple detection of pressure leaks to determine a materials compliance in quality-control
testing.The instrument, which runs using the Windows® operating system, has a holder for the test
material sample. With a press of the space bar on the computer keyboard, it calculates the
materials leak rate in as little as 30 seconds at pressures of up to 20 pounds per square inch
(psi). Results are reproducible, and different materials may be tested under different conditions.
The instrument stores all data, which is transferable to other locations and can be used by other
software packages, according to the company.
