Walk-in dust and sand test chambers are designed to simulate natural sandstorm conditions to test the protective performance of large equipment, while IP56X dust and sand chambers focus on shell sealing detection and are suitable for small and medium-sized electronic and electrical products.

Temperature control devices in salt spray test chambers regulate temperature variations in the working environment. These devices utilize physical changes within their mechanisms to trigger specific responses, such as opening or closing circuits, thereby achieving automatic temperature control.

During the operation of your high/low-temperature humidity test chamber, moisture can accumulate due to temperature fluctuations. To prevent this from affecting test results, it's essential to maintain the dryness of the equipment.

If a UV aging test chamber is not wired correctly, the equipment will not function properly. Therefore, wiring is a fundamental task.

Salt-spray corrosion testing is the primary accelerated method for validating the corrosion resistance of materials and their protective coatings. Whether a chamber can continuously generate neutral (NSS), acetic-acid (AASS) or copper-accelerated acetic-acid (CASS) salt fog for 48 h–1 000 h determines the repeatability and reproducibility of the test.
