Basic introduction:
The electrothermal constant temperature vacuum drying oven is a modern drying tool specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances. At the same time, it can maintain a certain degree of vacuum in the studio, and can fill the interior with inert gas, especially some articles with complex components, which can be dried quickly. Intelligent digital thermostat is used to set, display and control the temperature. At present, it is widely used in biochemistry, chemical pharmacy, medical and health, agricultural scientific research, environmental protection and other research and application fields.
Features:
1, the shell adopts electrostatic spraying process, and the paint film is stable and reliable;
2. Various temperature control instruments can be selected, with high temperature control accuracy and good stability;
3. The door of the box is sealed with silicone rubber strip, and the sealing effect is good.
General operation process:
1. The box is placed in a dry place indoors and no other fixing devices are needed.
2. Install the iron case knife switch on the special power supply line of this box, and use the wire twice the thickness of the power supply line as the grounding wire and effectively ground it.
3. Before electrifying, check whether the voltage in this box is consistent, and convert the current according to the total working rate, and connect the power cord with corresponding specifications.
After everything is ready, you can put in the sample, close the door of the box, and then you can turn on the power and start working.
5. Don't dismantle the side door at will to disturb or change the line. Only when the box is broken can you remove the side door and check one by one according to the line. If there is any major fault, please contact our factory and maintenance point.
6. Turn on the power heating switch after turning on the power supply, and when the required temperature is higher than 150℃, adjust it to high temperature. Otherwise, there is no need to turn on the high temperature, just turn on the power switch, and then turn the thermostat knob clockwise from the "O" position to the required temperature point. At this time, the temperature in the box begins to rise, and the green light of the instrument lights up as an indication. At the same time, you can turn on the blower switch to make the blower start working.
7. When the temperature rises to the required working temperature, the green light turns off, the red light turns on, and the indicator light turns on and off alternately, which is the constant temperature fixed point. At the constant temperature point, it is likely that the temperature will continue to rise, which is due to the influence of residual heat and will tend to be stable after about half an hour. When the indoor temperature is stable, the red numbers 10 1A and 202A indicate that when the reading exceeds or falls below the required temperature, the knob can be slightly adjusted to reach the correct level.
8. After constant temperature, it can be kept constant for a certain time according to the needs of the test. In this process, the temperature can be automatically controlled by the thermostat in the box without manual management.
9. If you want to observe the sample in the studio, you can open the door of the box and observe it through the glass door or observation door in the box. However, it is not advisable to open the door frequently to avoid affecting the constant temperature, and when the temperature rises to 300℃, opening the door may cause the glass door to suddenly cool and break.
10. Please read the instrument manual when using this box.

In addition to understanding the basic situation and operation process of the drying box, we also need to pay attention to the maintenance of the drying box in daily use. Especially in order to avoid circuit burning, it is necessary to check whether the power supply voltage is consistent with the rated voltage of the box before using the drying box. Because the electrothermal constant temperature drying box has electronic equipment such as temperature controller, it is not allowed to put the box in a corrosive environment containing acid or alkali. In addition, it is worth mentioning that volatile goods and inflammable and explosive goods must not be put into the oven, otherwise it will easily cause explosion. After all, safety is the first priority. The electrothermal constant temperature drying oven is introduced here first, hoping to help you.
