Introduction Dj-500p demagnetizer has the biggest demagnetizing surface at the flat demagnetizer. It is the leading level at the demagnetizer surface, power consumption and work efficiency in china. It can produce a damping magnetic field.And it need not move the workpiece during demagnetizing.Based on fully taking into account demagnetisers reliability andstability , the design and special selection of materials make dj-500p type demagnetizer to be widely used. Dj-500p demagnetizer do not pollute the powerline.Large parts, large devices (such as calipers, needles, screws, nuts, change knives, scissors, blade) can be demagnetized easily. Major technical character 1. Application: magnetic metal parts and molds. 2. Demagnetized voltage (v): ~~ 380v 3. Demagnetized time (s): 2-5 s 4. Demagnetized area (mm): 500 ~{!a~} 500 5. Residual flux:
