Why buy Thermotron AST Series HALT /HASS Chambers and what is so unique of those?

Three Modes of Operation

  • Low Frequency: Excites products more effectively, which is especially important for larger, mechanical products with lower resonant frequencies
  • High Frequency: 100+ Grms levels, decreasing the time to find product failures.
  • Synchronized Shock: High G shock can be delivered in a wide range of discrete frequencies, it accelerates the rate of fatigue accumulation

Soft Start:

  • Unlike other systems that generate spike at 1g or low, AST series can simulate precise low g levels without spike.

Dual Strike Impactor

  • Multi-Zone Control: Multi-Zone Vibration Control is the first of its kind. Users can choose from one, two, or four table zones and test different-sized products at the same Grms level and stress same-sized products at different Grms levels.
  • AST Control system: The AST-8800 control system features a Windows®-based graphical user interface. The controller can be configured to monitor run-time on wear items and automatically alert the operator when periodic maintenance is required.
  • Multiple Sizes to Suit your Needs: AST standards series are available in 8, 18, 35 & 70 with variety of table sizes that would meet most of your HALT /HASS testing needs.
