| Product List |
Walk-in constant temperature and humidity testing machine is designed for comprehensive environmental testing of complete machines or large-scale components. It provides precise control over low temperature, high temperature, temperature cycling, constant humidity, heating, and alternating temperature-humidity conditions. This chamber offers industrial-scale temperature and humidity testing environments for large parts, semi-finished products, and finished goods.
The system features a modular enclosed cabinet design with an attractive appearance and scientifically engineered air duct configuration. Key components include control panel, switchboard, moisturizing base plate blower, heating system, humidity system, and refrigeration unit. Custom chamber sizes and functions are available to meet specific customer requirements.
Suitable for heat resistance and cold resistance testing across multiple industries including:
