40 ℃plusmn; 0.5 ℃ 90% plusmn; 2% RH;

4. Wind speed range: 0.02~0.8m/s

5. Wind speed adjustment method: automatic adjustment, manual adjustment;

6. Moisture permeable cup holder layer: three layers;

7. Quantity of moisture permeable cups: 18 second layer (optional for national, American, and British standards)+6 first layer using Japanese standard potassium acetate method;

8. The rotation speed of the breathable cup holder is adjustable at 2rpm/min and 5rpm/min;

9. Power supply: AC220V plusmn; 10%, power: 4KW.

Technical features:

1. The refrigeration system adopts a French Taikang refrigeration unit to ensure long-term stable operation of the entire machine;

2. Adopting Swiss imported temperature and humidity sensors to ensure the accuracy of temperature and humidity inside the experimental cabin;

3. Adopting industrial color touch screen operation, displaying menus in both Chinese and English;

4. Adopting automatic water addition function for easy testing and suitable for long-term testing needs;

5. The temperature and humidity recorded every minute can be queried in real-time and can be connected to a printer for printing output;

6. Adopting a three-layer sample placement rack with 9 test cups per layer greatly increases the number of single test samples, reduces user operating costs, and improves efficiency;

7. The sample cups are equipped with small doors to reduce the impact of the sample collection period on the test environment and shorten the time for re stabilization;

8. In full compliance with the provisions of Article 5.1.1 of IOS12704~2009, balance must be reached again within 3 minutes after each closure of the test cabin door;

9. The turntable specimen placement rack is more uniform in testing than the fixed specimen rack.
