Instrument features:

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

2.The temperature and humidity sensor imported from Switzerland is adopted to ensure the accuracy of the temperature and humidity in the experimental cabin;

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

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

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

6.Two layers of sample placing rack, each layer9 test cups, greatly increasing the number of samples in a single test, reducing the user's operating costs and improving efficiency;

7.The sample cup is respectively provided with small doors, which reduces the influence on the test environment after the sample is taken for a period of time and after the door is opened, and shortens the re-stabilization time; (fully in lineGB/T12704 ~ 2009 5.1.1 each time after closing the test compartment, must be balanced again within 3 minutes);

8. The turntable sample placement rack is more uniform than the fixed sample rack.
