The Walk-in Constant Temperature and humidity Test Chamber is designed to expose products, components, and materials to controlled temperature and humidity environments to evaluate their performance and reliability under various conditions. This equipment is widely used in environmental simulation and reliability testing for electrical and electronic products, as well as other industrial components and materials. It supports constant high/low temperature testing, temperature/humidity cycling tests, and gradual temperature/humidity change tests.
This constant temperature and humidity test chamber conforms to the following IEC standards and clauses:
• IEC 60068-2-1: Environmental testing – Part 2-1: Tests – Test A: Cold
• IEC 60068-2-2: Environmental testing – Part 2-2: Tests – Test B: Dry heat
• IEC 60068-2-3: Environmental testing – Part 2-3: Tests – Test Ca: Damp heat, steady state
• IEC 60068-2-30: Environmental testing – Part 2-30: Tests – Test Db: Damp heat, cyclic (12 h + 12 h cycle)
The following samples are not permitted to be tested or stored in this chamber:
• Flammable, explosive, or highly volatile substances
• Corrosive substances, biological samples
• Samples with strong electromagnetic emission sources
