The liquid inspection is mainly used in airports, stations, public places that have large stream of people to inspect metal goods, because many metal objects are threatening to the public safety, such like guns, controlled knifes and etc. Besides, the walk-through metal detectors also serve in many factories in order to avoid steal.

I believe that walk-through metal detectors are very common in our daily life. Actually, we can see them many times a day. For example, every time we get into a subway station, there would also be a baggage security system. It seems that the baggage security system and the walk-through metal detectors are the most general combination in the field of security device. No matter who you are, your daily routine would always include at least one link that is to go through them. However, the existence of cargo inspection should be unwelcomed. Unless the terrorism is more and more rampant, there is no need for the security devices. What is more, there are several tragedies that are caused by terrorism attack these years. We have to doubt about everyone who is going to enter public places with a premise that everyone could be a terrorist. But what we hope it to be is that there is no terrorism. Everything can be dealt with in a gentle way. Since the invention of metal detectors, it creates the possibility for security devices. As most of the safety-threaten object are made of metal, metal detectors seem to be born to be security devices while they are not. Compared with hand held metal detectors, walk-through metal detectors are much more efficient.

The only thing we have to do is to walk through the metal detector door. It is just like that we walk through any other doors. As a matter of fact, walk-through metal detectors save a lot of time that used to be paid on the security checking. What is more, the walk-through metal detectors help maintain social order. But this should also thank to the high efficiency of them. The walk through metal detector is also based on the electro-magnetic introduction. So the working principle is similar to general metal detectors. In my opinion, the most remarkable advantage of walk through metal detectors is that they use the door shape to set the metal detectors. Though the existence of security device make a promise that everyone is doubted to be bad, no one want to be like that. In this way, direct checking does harm to the feeling of people. While x-ray security machine masterly avoid this. The idea of “door” keeps away from the embarrassment. Walk-through metal detectors make it nature to check up, because there would always be doors. No one would feel strange to pass a door. Even it is not same as the general ones.
