Benchtop Temperature Humidity Test Chamber aims to test new materials/products performance under high low temperature alternating climate condition,the purpose is develop and manufacture qualified products, benchtop temperature chamber is especially designed for laboratories with narrow space.

Benchtop Temperature Humidity Test Chamber capacity is from 22L-50L,Temperature range: -40°C to +130°C,humidity range: 30% to 95% RH.


  • Working chamber made by anti-corrosion SUS#304 stainless steel
  • Programmable LCD touch screen controller
  • Original imported France “Tecumseh” compressor
  • Uniform air circulation inside working chamber by low noise blower
  • Reinforced silicone rubber door sealing,which avoids aging and hardening under extreme climate condition.
  • 25mm diameter cable port locates at left side of chamber
  • Transparent viewing window made by reinforced tempered glass
