Description

Akustron Air Permeability Tester

A quick and reliable permeability test on the move or in the lab

Easily transportable, this unit is ideal for monitoring material on the production line, inspecting incoming material on-site and on-going quality control in the lab. Constructed of the most rugged materials, the AKUSTRON withstands the demands of constant usage.

 

Test description

Automated testing ensures there are no user related variables.
The sample is inserted into the slot, and the lever is pulled forward.
This clamps the sample and begins the testing automatically. The
method of measurement is based on two, long-life approved speakers.
The speaker in the lower enclosure generates an oscillating air-column
which displaces air through the test sample. A second speaker in the
upper enclosure works as a sensor and measures the amount of air that
passes through the clamped sample. The measurement is completed in
about 3 seconds, and results are shown immediately on the integrated
digital display. An RS-232 interface is able to send the test data
directly to a PC.

AKUSTRON software is included and automatically displays the test
data into an already opened spreadsheet. The data can also be
downloaded directly to a company’s existing quality control program.
