HALT HASS Test Chamber

Our HALT and HASS test chambers combine extreme temperature transition rates with random vibration to quickly help discover product defects.  These chambers utilize a liquid nitrogen cooling system to provide the rapid thermal change rates required to achieve maximum product stress. The vibration table is a six degree-of-freedom (6DoF) x,y,z axis creating real-world vibration conditions.  Table acceleration levels can be mounted and controlled via a tri-axial accelerometer block, or single Z-axis control.
