SIGMA HALT-HASS Test Chambers

The Sigma Series of liquid Nitrogen-cooled HALT-HASS random vibration testing chambers has been specifically designed to interface with a pneumatic multi-axis vibration table, offering a combined environmental test of rapid temperature change and random vibration. The chamber is interfaced with a patented vibration table offering high energy, broadband random vibration with six degrees of freedom. Vibration can be input during pre-selected temperature ramps, dwells or independently. The chamber is available with a choice of vibration table sizes. The temperature range of the chamber is -100°C to +200°C with temperature rates of change up to 80°C/min.
