HALT & HASS Chambers

Accelerated Stress Testing

HALT and HASS Time Compressor® chambers provide extreme temperature & vibration capabilities used during the product design and manufacturing cycles to compress the time normally required to identify design and process weaknesses. HALT techniques are important in uncovering many of the weak links inherent to the design and fabrication process of a new product. HASS techniques are incorporated during the production phase to find manufacturing process defects that could cause product failures in the field.

Industry leading performance levels of these CSZ HALT and HASS chambers include temperature ramp rates greater than 90ºC/min (194ºF/min) with vibration levels of 1 to 90 GRMS for accelerated stress testing. Sound levels, liquid nitrogen consumption and power usage are the lowest in the industry offering compelling return on investment opportunities.

Touch Screen Controller
  • CSZ EZT-570 Touch Screen Controller with data logging, remote control & monitoring, email/text alarm notification messages, data file backup system, full system security and more.  Includes pre-programmed test profiles for faster program implementation.
EZ-View Software
  • RS-232/485 serial communications
  • EZ-View works with EZT-570 controller to provide remote monitoring, control, data logging and store/graph measured temperature and vibration GRMS data. This software is provided as a no cost value added feature.
Halt Hass Testing
  • High temperature ramp rates at >90°C (194°F) per minute for increased thermal stresses to speed precipitation.
  • Low LN2 and power consumption in total for a given screen dramatically decreases operating costs.
  • Pressure gauges allow operating pressures to be continuously monitored.
  • Large dynamic range shaker, 1  to 90 GRMS with a bare table. High GRMS levels are used to enhance precipitation and low level with Modulated Excitation™ are used to increase detection.
  • Lowest noise level < 72 dBA at 30 GRMS.
  • One size chamber can accommodate wide range of product weights/sizes for high payload weights using replaceable springs.
