Airmatic Burst Tester

For determination of bursting strength and bulging height of filter papers, elastic foils and aluminum foils. The burst tester is equipped with an electronic sensor to measure burst pressure, as well as an optical sensor to measure bulging height. The system can optionally be supplied with an optical porosity detector. This detects pores created during the burst test. Sample clamping is pneumatic, with the ability to preset the clamping pressure. The clamping bell is surrounded by a safety guard to prevent injury and is also equipped with a suppressor. A pivotable touch screen is attached to the side of the unit, which can be used to define all unit parameters. The burst tester is equipped with a standard FRANK-PTI connector.

Test description

The touch screen is used to set the necessary parameters depending on test method (burst strength bulging height and/or pore detection). The sample is placed in the burst tester and the start button is pushed, causing the clamping bell and safety guard to lower, and the selected test procedure begins. First, the sample is clamped at the preset pressure and then air is blown under the sample (aluminum foils) or into a rubber membrane (filter papers), causing the sample to bulge until it bursts, to the preset bulge height, or until a pore is detected. According to requirements, the individual values, diagrams or statistics can be read from the touch screen.
