[Instrument Features]:

1. The refrigeration system adopts the French Taikang refrigeration unit to ensure the whole machine to run stably for a long time.

2. Temperature and humidity sensors imported from Switzerland are used to ensure the accuracy of temperature and humidity in the experimental cabin.

3. Using industrial color touch screen, Chinese and English menu;

4. The instrument adopts automatic water filling function, which is convenient for testing and suitable for long time testing.

5. The temperature and humidity recorded once a minute can be checked in real time, and can be connected to the printer to print out;

6. The two-layer sample placing frame and nine test cups per layer greatly increase the number of single test samples, reduce the operating cost of users and improve efficiency.

7. The sample cups are respectively equipped with small doors, which reduce the impact on the test environment after opening the door due to the time of taking samples, and shorten the stable time again; (In full compliance with Article 5.1.1 of GB / T12704-2009, each time the test hatch is closed, the balance must be reached again within 3 minutes)

8. The test is more uniform than that of the fixed sample holder.
