The DHT® Double-Door Temperature Test Chamber adopts an innovative dual-door (cascade) design, specifically engineered to overcome the limitations of traditional single-door configurations. This advanced structure facilitates the placement and retrieval of large-sized samples while maintaining exceptional temperature control performance. DOHO’s R&D team integrates cutting-edge temperature control technology with precision manufacturing to ensure uniform internal temperature distribution and robust sealing integrity, even with the dual-door configuration. Balancing efficiency and flexibility, this chamber delivers high-precision thermal performance and accommodates diverse sample dimensions, making it an ideal solution for rigorous high/low-temperature testing.
