1. Single-channel dual-drum, synchronous operation: It adopts a single-Channel dual-drum design, allowing both drums to operate simultaneously, significantly enhancing the detection efficiency.
2. Precise control, intelligent and convenient: The instrument automatically and precisely controls the rotation speed and number of rotations of the drums, ensuring the stability and repeatability of the experimental parameters.
3. Transparent material, clear observation: The drums are made of high-quality acrylic glass, which is colorless and transparent, facilitating clear observation of the sample status during the experiment.
4. Dual-screen real-time monitoring: Equipped with dual LCD screens, it separately displays the preset values and real-time values, allowing the operator to easily grasp the experimental parameters.
5. Automatic timed shutdown, worry-free and labor-saving: It has an automatic timed shutdown function, which can accurately stop the operation according to the preset time, eliminating the need for manual supervision.

Environmental requirements:
1. The ambient temperature should be controlled within 20 ± 10℃, and the relative humidity should not exceed 85%.
2. For moisture-absorbing samples, the ambient humidity should be kept below 40% to prevent moisture absorption from affecting the test results.
3. The sample surface should be clean, dry, and free of impurities.

Precautions:
1. Set the test parameters correctly, such as rotation speed, time, and count.
2. Avoid changing the working mode randomly during the experiment.
3. Prevent the equipment from being shaken or disturbed by humans during the test.
4. Carefully position and firmly secure samples to prevent slipping or ejection during the test.
5. Operators should wear protective gloves and goggles to avoid eye and hand injuries from sample splashes or fragments.
6. Do not allow fingers or other objects to approach the samples or clamps during the test.
7. Untrained or inexperienced personnel are not allowed to operate the instrument at will.
8. After the test, promptly clean the surface and interior of the instrument to remove any residual samples to avoid affecting the next test.
9. Use a clean soft cloth and appropriate cleaning agent for cleaning. Do not use hard objects to damage the instrument surface.
10. Regularly inspect the electrical components, mechanical parts, etc. of the instrument.
11. Regularly calibrate the instrument to ensure its accuracy and reliability.
12. Regularly maintain the instrument components, such as cleaning the distributor and grinder, and replacing worn parts.
13. After the test, turn off the power and unplug the instrument.
14. Store the instrument in a dry, clean, and non-corrosive gas environment.
