However, there are more and more kinds of metal detectors appearing in the market. All of them have a not low price. So, not everyone who needs one metal detector can buy it. What I want to talk about is that how we can choose a cheap metal detector door that can still appeal to our needs. Maybe, these cheap metal detectors don't have the enough functions, but they still can match daily need. Next, let me teach you what we can do that can help us to choose one cheap metal detector.
Know about the functions well
Choosing a most suitable to you, not expensive, is the most important when you go to choose a metal detector. Nowadays, the x ray baggage scanner price in the market often have much more functions than you really need to use. And, these metal detectors always very expensive. First, you should know about where you really want, and, also, the function. Then you can choose one relatively cheap metal detector. Maybe, someone will ask WHY. Why we can choose a cheap metal detector just do like what I ask? Let me tell you. You can choose a cheap one because it doesn't have much function, it just fit to yours. So, the price will be low compared to the one which has more functions. Now, you may don't know the functions well. Let me introduce to you everyone.
1. Hand held metal detector
What can this type of the x-ray security machine do? It is firstly used in airports, workshops, docks, preaching, and venue public security. The volume of it is not big. It can be held in our hands and then use it to detect the body of us if there are any metals in it. However, with the development of the society, this type of the metal detector is not usually used in these places. Nowadays, these X-ray baggage Inspection system is often used in the exam places. It can help the teacher to detect if students bring something illegal that will help them to cheat. And, this one is not expensive now. If you need this function, you can choose this one type.
2. Door frame metal detector
Just like what I said above, those X-Ray baggage scanner are not used in the big public places now. What is used in those places is door frame metal detector. Nowadays, there are more and more people. So, in the public, if you still use the hand held metal detector, you will find it have low efficiency. What they need is to have higher speed and more efficiency. But this type metal detector is seldom used in our own places, so I introduce it little.
Of course, there are more and more types of the metal detectors. Remember one, choose what you need only. You can buy the cheap metal detector.
