Gelbo Flex Resistance Tester

Gelbo Flex flexing chamberTest principle:

The sample in the test chamber experiences a comprehensive effect of torsion and compression. During the process of torsion, the air is drawn from the chamber and the particles in the air are counted and classified using a laser dust particle counter.
