The periphery of the inner container adopts circular arc transition, and a toughened glass door is arranged inside the inner container.

2. The machine adopts the intelligent microcomputer LCD control system and has the functions of timing, alarm, over-temperature protection, etc. The 30 sections of temperature and humidity setting and automatic switching fulfill the function of simulating the environmental temperature and humidity.

3. The Brand compressor achieves fluorine-free and environmentally friendly refrigeration and breeze circulation to ensure uniform temperature inside the box.

4. Balanced control over cooling and heating ensures small temperature fluctuation and more accurate temperature control.

5. The independent glass front door observation window is transparent and beautiful, which is convenient to observe the changes of the items in the box. The magnetic rubber seal is used, and the door is easy to open and good in sealing performance.

6. The steam humidification is adopted, The internal humidity is stable, the humidity fluctuation range is ±3%RH, and the automatic water replenishment function and the water shortage and power off function are fulfilled to prevent the machine
from burnout due to water shortage.

7. The machine has multiple safety measures, such as compressor overheat protection and instrument failure protection, to ensure the safety of the tests.

8. The intelligent defrosting system is adopted to ensure that the machine does not frost when running for a long time.

9. The machine has the one-button drainage function, and the operator can press the drainage button to discharge water after the machine stops.

1. Preparation stage

Before use, fill the humidifier bucket with purified water or distilled water and place it on the right side of the machine. Connect one end of the silicone tube to the "humidifier water inlet interface". The other end of the silicone tube is inserted into the humidifier bucket and does not cross the water surface. In addition, prepare a 1500ml bottle by yourself and insert two drain pipes into the bottle.

2. Start the machine

Turn on the power switch for about 3 seconds, display "end" in the lower row of the instrument, long press the "increase" button for about 2 seconds, and the machine enters the running state. At this point, the temperature and humidity can be set according to the instructions.

3. Set the state

In the machine running page, press "set" button, enter the state of cycle and set the section number, cycle value, click on the "add" or "reduce" button to modify the cycle value (the cycle generally is set to 0 cycle), and the cycle is set up. Then click the "set" button, display the number of set point, click on the "add" or "reduce" button to modify the section number and the number of set up, and then click the "set" button to enter the next parameter Settings page to set the time, temperature and humidity state, and click on the "add" or "reduce" button to modify the corresponding values. After setting the corresponding period, number of segments, temperature, humidity and time, click the "set" button to save and exit, and then the machine starts to run.

If the machine is not used for more than 24 hours after shutdown, click the "drain button" after power off, the water in the humidifier of the machine will be automatically discharged.

In the setting state, click the back key to return to the setting of the previous parameter, and the selected parameter value will blink to display. Short press the exit or set key to exit the setting state, save parameters and lose power memory.

Note: One cycle means that the controller runs from the first segment to the Nth segment (the number of segments required by the customer) for one cycle. When the cycle is set to 0, it means that the controller is located in the continuous working state.
