The Qualmark Typhoon 1.5 (OVS-1.5) is a compact environmental test chamber designed for Highly Accelerated Life Testing (HALT) and Highly Accelerated Stress Screening (HASS). It combines rapid thermal cycling with omni-axial six-degree-of-freedom repetitive-shock vibration to accelerate product failure modes and validate design robustness in accelerated timelines.
