Millions of people around the world walk through metal
detector gates every day. Not only the airports, but also government agencies,
jewelry stores, casinos, night clubs and a lot of other venues uses these gates
to enhance security level and to ensure the safety of every one present. A
light weight, portable walk through
metal detector is advisable for you if you intend to move it quite frequent
or use it on multiple locations. Contrarily, if you are not intending to move
it, buying a fixed metal detector gate is the right choice.
With the advancement in technology, there is a great visible
change you can see in the field of metal detectors as well. Keeping things
simple, there are single zone and multi zone walk through metal detectors. Now what is the main difference in
between the two? The first type only detects if you are carrying any type of
metal with you or not. The second type pinpoints the body part on which you are
carrying the metal body. So before you choose any model for your establishment,
you must know the exact purpose the detector will be used for. One more thing
to keep in mind is, if you are going to place the unit outdoor, it must be
weather proof.
A walk through magnetometer creates big magnetic field that cover all
the room available within the rectangular archway of the walkthrough metal
detector. A normal magnetometer based walkthrough gate sends almost 120 pulses
in a second. This count can vary from one model to another and the precision
level the machine is designed for. When a person crosses walk through magnetometer and the security alarm sets on, the
security personal gets the information about the person hiding a gun or a
knife. The latest metal detector gates are far more advanced and have made the
work easier for the operators.
