1. Unwanted recordings may simply be erased by demagnetizing. 不需要的录音只要退一下磁就可以抹掉。
2. The conventional demagnetizing method is not good at inner demagnetization using direct or alternating magnetic field. 常规的交、直流消磁方法对材料内部消磁效果欠佳。
3. A self reset type button is arranged to control the demagnetizing operating program and the detecting operating program. 设置了自复位式按钮控制去磁和检测两个操作程序。
4. Digital pulse demagnetizer has better demagnetizing effect and can increase the efficiency of classification and screening. 数字脉冲脱磁器是一种新型脱磁器，其脱磁效果好，明显提高。
5. Ithas achieved the intelligent control of the process of magnetizing and demagnetizing, on-line measurement and calibration. 实现对充、退磁过程的智能化控制，剩磁强度的在线测量及校正；
