Corona treatment pens typically use models DC-3000 or higher.
1. Function of a Corona Treatment Pen
A corona treatment pen is used to measure the surface potential of a carton. By measuring the high-voltage electrical signal generated by the corona treatment pen on the carton surface, it determines whether the carton surface is charged, thereby testing the electrostatic quality of the carton and ensuring its safety during use.
2. Applicable Models
Corona treatment pens come in different models, including the DC-2000, DC-3000, and DC-4000. Models DC-3000 and higher are suitable for measuring paper or cardboard with a thickness of 0.05mm or higher. Therefore, when measuring carton thickness, a DC-3000 or higher is generally recommended.
3. Measurement Steps
1. Turn on the corona treatment pen and wait approximately 30 seconds for the pen to preheat.
2. Place the carton on a level surface, ensuring that the surface is completely flat.
3. Hold the corona treatment pen's probe vertically against the carton surface while pressing the test button on the pen to begin measuring.
4. Use the test results to determine whether the carton surface's electrostatic quality meets the requirements.
IV. Precautions
1. Pay attention to safety when using the corona treatment pen. Avoid bringing the pen's probe close to your body to avoid injury.
2. Keep the carton surface completely flat during measurement to avoid deviation.
3. Before using the corona treatment pen, ensure it is fully preheated, as this will affect test accuracy.
In summary, corona treatment pen models DC-3000 or higher are generally used for carton testing. Proper use ensures the quality and safety of the carton.
