How To Select Our Walk Through Metal Detector
- Dec 18, 2017 -

Walk through metal detectors fall into several general categories according to the different zones. The first style of walk through metal detectors provides 4 zones detection, such as AT100A,100B,100C. The second style provides 6 zone detection. Basic 6 zone detectors like the AT200A,200B,200C. The third style provides 18 zone detection, such as AT600C. The forth style provides very high precised detection, such as AT 1008 series. In addition, there’s some special function metal detectors, such as AT500, which can be used outside. AT007, which can be unfolded and very easy to be carried. At008, which can detected separately and identified the magnetic and non magnetic. AT300 series, whoes gateposts are elliptic.
One of the most important features to look for in a walk-through metal detector is a wide range of sensitivity settings. Contrary to popular belief, it is not always ideal to keep your metal detector on the highest possible sensitivity setting.
Highly sensitive detectors do indeed pick up metal easily, but they are also more susceptible to interference from local transformers, radio signals, or trace amounts of metal in your building. Such interference may lead you to detect metal on a student who has none, causing you and your staff to waste time inspecting that student. The more sensitivity settings, the easier it is to compensate for such problems.
Buy a model that is lightweight and easy to move. The easier it is to transfer your metal detector from one doorway to another, the better you can plan for special occasions. Most occasion have events in which relying solely on the primary entrance is difficult. Say your occasion's gym is far from the primary entrance, and you plan to hold a dance there. Do you force people to enter the primary entrance and walk all the way to the gym, or do you take the risk of letting them use a closer entrance?
Finally, make sure to buy a walk-through metal detector that can resist outside tampering. Whether as a prank or to bring metal objects into the occasion, computer- or tech-savvy people may interfere with your metal detectors, either physically breaking them or using software to compromise their detection abilities. This can cost you hundreds in repair while leaving you vulnerable to security risks. Tamper-proof metal detector settings can counter hackers, while sturdy overhead caps can prevent damage from the weather and physical attacks alike.
