Understanding the DK-3 Electric Sand Bath
The DK-3 Electric Sand Bath, also known as the electric sand bath, temperature-controlled electric sand bath, and sand bath electric furnace, is a versatile piece of equipment designed for various applications in industries such as mining, healthcare, environmental protection, biochemical research, and educational institutions. It is primarily used for chemical analysis, physical measurements, and thermal treatment of items, including baking, drying, and other temperature tests.
Structure and Design
The DK-3 Electric Sand Bath is constructed with a high-quality cold-rolled steel plate, which is pressed and welded to form the outer shell. The surface is treated with electrostatic spraying technology for durability. The working chamber is made of stainless steel or cast iron, which is then treated for corrosion resistance. The heating pan is fully enclosed, eliminating the risk of open flame, ensuring quick and safe temperature rise.
Features and Usage
The DK-3 Electric Sand Bath is equipped with a digital display P.L.D. control device, which offers temperature setting, automatic temperature control, and digital display. Here’s how to use it:
- Place the instrument on a platform or worktable.
- Connect the power supply and turn on the power switch. The indicator light will illuminate, indicating normal operation.
- The instrument will display the room temperature. Press the green button to turn on the heating, and the red button to turn off the heating and maintain the temperature.
- The red and green lights will alternate, indicating that the instrument has entered the constant temperature state. After about 30 minutes of constant temperature, the working chamber temperature will be relatively uniform.
- To change the set temperature, adjust the code switch on the control panel.
- After completing the work, turn off the power supply.
Operating Conditions
The DK-3 Electric Sand Bath should operate normally under the following conditions:
| Parameter | Value |
|---|---|
| Temperature | 2-40掳C |
| Relative Humidity | Not more than 85% |
| Power Supply Voltage | 220V 卤10% |
| Frequency | 50Hz 卤1Hz |
Precautions
Here are some important precautions to consider when using the DK-3 Electric Sand Bath:
- The power supply voltage must match the requirements of the product.
- The instrument’s outer shell must be effectively grounded.
- Place the instrument in a well-ventilated room with a relative humidity of not more than 85%. Avoid placing flammable, explosive, and corrosive items around the instrument.
- During the heating process, the working chamber may produce smoke, which is a normal phenomenon. This is due to the combustion of anti-rust agents on the surface of the working chamber.
Conclusion
The DK-3 Electric Sand Bath is a reliable and efficient tool for various applications in laboratories. Its advanced features, such as digital temperature control and corrosion-resistant materials, make it an ideal choice for researchers and professionals in various fields.
