Hanse Environmental will be introducing ED-HALT vibration into their integrated high rate temperature chambers. This will bring the Worlds first 6 MDoF (Multi Degree of Freedom) Spherical random, compact Electro-Dynamic (ED) repetitive shock. This new vibration HALT system give faster results. The Next Great HALT Breakthrough from King Design. This replaces the standard AIR impactor with an Electro Dynamic (ED) impactor with precise time and phase control. Producing low frequency vibration form the 20-2000 Hz.
