The electric constant temperature vacuum drying oven is designed specifically for drying heat sensitive, easily decomposable, and oxidizable substances. At the same time, it can maintain a certain degree of vacuum in the working chamber and fill the interior with inert gas. Especially for some complex components, it can quickly dry. It is a modern drying tool that uses an intelligent digital temperature regulator for temperature setting, display, and control. Currently widely used in research and application fields such as biochemistry, chemical pharmaceuticals, healthcare, agricultural research, environmental protection, etc.
Operation process of electric constant temperature vacuum drying oven:
1. The box is placed indoors in a dry and level place, without the need for other fixed devices.
2. An iron shell knife switch should be installed in the power supply line for this box, and a wire twice as thick as the power line should be used as the grounding wire and effectively grounded.
3. Before powering on, check if the voltage of this box matches, and calculate the current based on the total working rate. Connect the corresponding power cord.
4. When everything is ready, the test sample can be placed, the box door can be closed, and the power can be connected to start working.
5. The side door cannot be removed arbitrarily, causing confusion or changing the circuit. Only when the box malfunctions, the side door can be removed and checked one by one according to the circuit. If there is a major malfunction, please contact our factory and maintenance center.
6. After connecting to the power supply, the power heating switch can be turned on. When the desired temperature is above 150 ℃, it can be switched to high temperature mode. Otherwise, there is no need to turn on the high temperature switch. Just turn the temperature controller knob clockwise from the "O" position to the desired temperature point. At this point, the temperature inside the box will start to rise, and the green light on the instrument will light up as an indicator. At the same time, the blower switch can be turned on to start the blower.
7. When the temperature reaches the required working temperature, the green light goes out and the red light comes on. The indicator light alternates between on and off at this point, which is the constant temperature setting. 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 stabilize after about half an hour. When the indoor temperature stabilizes, the red numbers of the 101A and 202A models will display. When the reading exceeds or falls below the desired temperature, the knob can be adjusted slightly to achieve the correct level.
8. After the temperature is kept constant, it can be kept constant for a certain period of time according to the needs of the experiment. During this process, an internal temperature controller can be used to automatically control the temperature without the need for manual management.
9. To observe the condition of the samples in the studio, you can open the box door and use a glass door or observation door inside the box to observe. But it is advisable to keep the door closed infrequently to avoid affecting the constant temperature, and when the temperature rises to 300 ℃, opening the door may cause the glass door to cool rapidly and break.
10. When using this box, please also read the instrument manual.
11. When using a new box, there should be humidity, which may cause hot air evaporation and paint burning smell. This is due to the evaporation of the constant temperature paint surface, which will disappear after one hour of use.
