Professional ozone test chamber with ortho-directional gas flow and heavy stainless steel body supporting the installation and use of static and dynamic testing tools of all kinds. Largest observation window for the surveillance of crack formation during the test with magnification optics or camera without stopping the test process by opening the chamber. Operation exclusively via touch panel. Each single rubber specimen can be advanced step by step into the optical observation zone. Mounting rails allow for the insertion of mesh plates and rod-like carriers for laying and hanging in all kinds of rubber test pieces, such as flat foils, tubes, cables, bushings and seals. The test system is intrinsically safe. The front door is electrically interlocked and can only be opened when the chamber is completely ozone-free. The test system is suitable for normal tests with regard to cracking, for the creation of Wöhler diagrams and for long life fatigue strength tests.
