Galaxy Series HALT HASS Test Chamber

Our Star Galaxy™ 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.

HALT and HASS Testing Benefits

  • Precipitates hidden or latent failures caused by poor workmanship or manufacturing processes.
  • Verifies integrity of mechanical interconnects
  • Prevents flawed units from reaching the end-user
  • Detects changes in components and processes
  • Decreases warranty and field service costs
  • Increased customer satisfaction
  • The innovative WEBSeason® user interface allows you to program, control and monitor your tests at any time and anywhere – even from your tablet or smartphone
