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. Use three layers of sample placing racks, each layer9 test cups, greatly increasing the number of samples in a single testReduce the user's operating costs, improve efficiency;

7. The sample taking cups are respectively provided with small doors to reduce the impact on the test environment after opening the door due to the sample taking period of time,Reduced re-stabilization time; (fully compliantEach time specified in Article 5.1.1 of GB/T12704 ~ 2009After the test hatch is closed,Equilibrium again in 3 minutes)

8. Turret type sample placing rack, the test is more uniform than fixed sample rack.
