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

technical feature:

1. The refrigeration system adopts the French Taikang refrigeration unit to ensure the stable operation of the whole machine for a long time;

2. Adopt the imported temperature and humidity sensor from Switzerland to ensure the accuracy of the temperature and humidity in the experimental chamber;

3. Using the industrial color touch screen operation, with the menu display in Both Chinese and English;

4. Adopt the function of automatic water filling, convenient for testing, suitable for long-term test needs;

5. The temperature and humidity recorded every minute can be queried in real time and connected to the printer print output;

6. Adopt three layers of test samples, with 9 test cups per each layer, which greatly increases the number of single test samples, reduces the operating cost of users, and improves the efficiency;

7. The test sample cup is equipped with small doors to reduce the impact of the test sample on the test environment after opening the door, and shorten the stability time again;

8. After closing the test cabin door in GB / T12704 ~ Article 5.1.1 of 2009, the balance must be reached again within 3 minutes;

9. The rotary sample is placed and the test is uniform than the fixed specimen.
