  • Overview of Equipment
  • Air-HAST

The Highly Accelerated Stress Test Chamber has been primarily developed to conduct bias testing which applies constant voltage and signals. The standard equipment features two control modes: [unsaturated control] and [wet saturated control], while the M-type chamber additionally offers a [wet and dry bulb temperature control] mode.

The M-type chamber conforms to the IEC60068-2-66 standard.
