ShockEvent T - Intelligent Features. Useful functions. ShockEvent T is a dual-chamber vertical shock. It compresses the transfer zone between the cold and hot zones with a transfer time. Between these two chambers, a basket with the test material moves at a certain speed. The time it takes to move the basket is the transfer time. In short, between the hot and cold chambers, it allows endurance tests of over 1,000 cycles to be run without defrosting.
