A Programmable Constant Temperature Humidity Test Chamber  is a testing instrument used to evaluate the performance of electronic components, materials, and products under high-temperature, low-temperature, or aging conditions. Its refrigeration system operates at room temperature, ensures stable and precise temperature control, and features adjustable air circulation. To maximize the lifespan of the test chamber, it is essential to understand its working principles and follow proper maintenance practices. Below are key guidelines to ensure its longevity:

1. Maintain cleanliness inside the chamber: Regularly clean the interior and remove accumulated water.
2. Inspect electrical control circuits: Ensure all connections are functioning properly.
3. Monitor equipment operation: Adjust refrigeration or heating systems to guarantee optimal performance under normal working conditions.
4. Control the ambient temperature: The external environment should not exceed 40°C (104°F).
5. Avoid direct sunlight or heat sources: Do not place the chamber under prolonged direct sunlight, near heat sources, or close to air conditioning vents.
6. Prevent moisture buildup: Keep the chamber in a dry environment and clean it regularly to avoid humidity absorption affecting test results.
7. Verify electrical safety: Before powering on, ensure all wiring is correct, connections are secure, and proper grounding is in place.
