The DHT® Walk-In & Drive-In Environmental Test Chamber is a high-performance environmental testing device designed to simulate complex environmental conditions. It is widely used across industries such as electronics, electrical appliances, chemicals, automotive, and aerospace. The device precisely controls temperature and humidity to provide stable environmental conditions for product reliability testing, ensuring performance evaluation under various extreme climates. The test chamber adopts advanced overall welding technology to provide robust, durable large (and extra-large) walk-in/vehicle temperature (humidity) test chambers. The integrated baseplate design facilitates the discharge of water and other liquids generated during tests, and the chamber can be installed on-site with full-welded construction, meeting the testing needs of large samples.
