HAST systems (Highly Accelerated Stress Test) are used for accelerated climate tests at temperatures of over 100°C with a controlled humidity.
The HAST test systems from ESPEC offer particularly user-friendly features: The large interior makes it easier to load PCBs. A condensation protection function for the heating and cooling phase, program control, 12 contacts for controlling the test specimens and an automatic water supply are included in the standard features.
A circulation fan ensures a homogeneous temperature and humidity distribution within the test chamber.
The HAST test systems satisfy the IEC 60068-2-66 standard and feature chamber volumes of 21 or 51 litres as standard as well as a dual-chamber system with two independent test chambers.
