Best Security Metal Detectors made in China: Top 8 (High sensitivity or Economic or Cheap choices)
Rating of metal detectors Models for detecting prohibited items are manual, arched (frame), and stationary. The first type - compact, mobile, allows you to inspect the visitor, personal belongings. Arched metal detector has good throughput. More often they are installed in places with a large flow of people: railway stations, metro, and airports. The stationary type (walkthrough metal detector) frees the visitor from inspection, guaranteeing safety. When selecting the nominees, we took into account not only the technical characteristics but paid great attention to the reviews of the owners of metal detectors, and reviews of independent experts. The criteria by which the best models were chosen are as follows: Throughput; Efficiency, the accuracy of verification; Ability to adjust the sensitivity; Operating temperature; Additional functionality.
The best handheld metal detectors are wearable compact devices. They are used to localize suspicious items carried under clothing, in hand luggage, luggage, or when the installation of an arched system is impossible for a number of reasons. We analyzed 8 models of hand-held screening metal detectors for your choices.
Today they can be seen even at the entrance to the offices of large companies - everyone is pleased to work in safety.
Among security metal detectors, arched or hand-held ones are most common. The first are metal arches through which visitors or employees pass. The second are small devices that are comfortable to hold in your hand and easy to carry.
Arched metal detector gates are used where a large flow of people passes through the detector every day. If the device finds metal in one of them, the guard conducts a more detailed examination with a hand-held detector.
In some cases, arched detectors cannot be used or they are inconvenient to place. Then only hand-held detectors work.
Who and how uses hand-held metal detectors?
The devices are designed specifically for various types of security services, but are also popular among treasure hunters. Their main task is to screen those who wish to enter the protected area. The detector will find the metal hidden under the clothes in a few minutes. With certain settings of the button and chain, he will not notice, the gun or knife will be easily detected.
How to choose the best metal detector?
The security device should be convenient and effective. When buying it, take a look at the following characteristics:
Sensitivity: Modern models recognize a pistol at a distance of 25 cm, a knife 15 cm, a bunch of keys from 10 cm.
Selectivity: When the metal detector works on every button or chain, after a couple of hours these false signals will overload your head so that you can miss a really important item. An instrument that can be adjusted to a specific size greatly improves the efficiency of inspections.
Indication: Depending on the size of the found object, a good detector gives a sound signal of different tones. When you constantly work with the device, over time you begin to understand by ear what is in the visitor's pocket. Some models can be set to vibrate so that the person being tested does not hear the signal.
Design: The case of a good detector is made of durable plastic, protected from water - with this you can inspect football fans in the rain. Weight can vary from 200 to 500 g. After checking 100 people in an evening, you will definitely want a lighter device. There is no large flow of checks - you can use heavy ones. Many models have a case and a belt clip.
Nutrition: Typically, detectors are powered by batteries or accumulators. The operating time without recharging is very important: the device should not be discharged in the midst of a work shift.
Analyzed these indicators and choose the detector that will be useful in your work.
