Metal detectors are electronic devices for detecting the presence of metal objects at various points of entry into buildings, events and such. The screening devices occur in two forms, handheld and walk-through. They may be used individually or co-currently to serve the same purpose and enhance entry point security.
Used as either a primary screening tool at screening points to detect metallic objects. They are designed for fast and efficient daily use, to accurately detect unauthorized metal objects such as knives and weapons. It is used in secondary screening to pinpoint targets detected by a walk-through metal detector.
ZK-D100S is powered by a built-in rechargeable battery. If metal is detected The device emits an alarm and blinks a red LED.
Walk through metal detectors are based on pulse induction (PI) technology. PI systems use a coil of wire on one side of the arch as the transmitter and receiver. This technology sends powerful, short bursts (pulses) of current through the coil of wire. Each pulse generates a brief magnetic field.
