Door Frame Walk-Through Metal Detector


The FMD-300C series through-metal detector door hereinafter referred to as the security door) uses international advanced metal detection technology, which is specially used to detect and prevent metal and alloy objects hidden in people. It has high safety, strong applicability, high sensitivity, adaptive adjustment sensitivity, wide detection range, strong resistance to external interference, 24 hours of intelligent service, simultaneous sound and light alarm, and achieved quality, effect, and technical parameters. The world's leading level. The sensitivity can be adjusted, the metal object with the size of the paper clip can be detected, and the location of the metal can be distinguished. The user can also set the size, volume, and weight of the metal to exclude coins, keys, jewelry, belt buckles, etc. False alarm. For places where it is necessary to prevent the loss of precious metal items, such as industrial and mining enterprises, banks, private luxury houses, etc., as well as places where it is necessary to prevent dangerous metal objects, such as airports, customs, prisons, exhibition halls, etc.
