Vacuum Test Chambers

The DHT® Vacuum Test Chambers is designed to meet the environmental testing requirements for temperature and humidity under high-altitude conditions. It is a long-life test chamber known for its high stability, precision, and low failure rate. With a capacity range from 100 to 1500 liters, it offers a temperature range from -70°C to +180°C (available in -20°C, -40°C, and 0°C settings). The temperature uniformity is even less than 1°C, ensuring it meets the stringent testing requirements of domestic, joint-venture, foreign-invested, and export customers.

Benefits

Advanced Control System: Equipped with an intelligent controller imported from Europe, the chamber is easy to operate, user-friendly, and highly stable, ensuring precise and controlled data during the testing process.

Optimized Air Circulation System: The specially designed air circulation system provides uniform airflow and precise testing conditions for the samples, ensuring the accuracy and repeatability of test results.

Precise Humidity Control: The optimized wet-bulb and dry-bulb humidity measurement system ensures highly accurate humidity control, essential for reliable testing under low-pressure conditions.

Air-Cooled Refrigeration System: Featuring a high-efficiency air-cooled refrigeration system, the chamber maintains stable operating temperatures even in low-pressure test environments, enhancing the durability of the equipment.

Self-Diagnosis System: Integrated with a self-diagnosis system, the chamber can detect and alert users to any operational issues, facilitating maintenance and repair, and ensuring continuous testing operations.
