What role does a hand-held metal detector play?
Hand-held metal detectors are designed to detect metal objects carried by persons or objects. It can be weapons, explosives or small metal parts in packages, luggage, letters, fabrics, etc. which are worn by persons. The special appearance of its sensitive surface facilitates handling. Better than ring sensor probes. Ultra-high sensitivity, special application. Such as prisons, chip factories, archaeological research, hospitals, etc.
Hand-held metal detectors (hand-held metal detectors, imported metal detectors) are used to check the specific position of the metal carried by the body, and can also be used with metal detector doors. If the "security gate" alarms and finds metal objects, use a hand-held metal detector to find the exact location of hidden metal objects. The metal detector adopts a rectangular detection head and the detection range is 12 cm long. When examining the human body, the inspection work is completed from top to bottom at once.
Which areas of application are there for hand metal detectors?
Factory protection:
The products of many factories contain metal components. To prevent the loss of company products, security forces check employees at the door of important workshops.
Prevention of audit fraud
In recent years, the university entrance exam, postgraduate exam, public service exam, and other exam rooms have prevented candidates from carrying other fraud tools such as wireless headphones. Each examination room is equipped with some hand detectors. Currently, many provincial education systems in the country are equipped with such products.
Public safety inspection
Such as airport security, prisons, courts, testing institutes, banks, hotels, large conferences, sports competitions, concerts and other public places.
How does using a hand-held metal detector work?
The power consumption of the hand-held metal detector is very low and any newly installed battery can work for about 50 hours. When the battery power drops to 10% the instrument can no longer function normally, and the speaker emits intermittent clicking sounds that prompt us to replace the new battery. In use, the safety inspector holds the handle with his hand, presses the start button with his thumb and releases it again, the signal light of the instrument starts flashing, at the same time the horn emits a very quiet hum, indicating that the instrument has entered the operating state. The staff scans back and forth on the surface of the subject (or object) when the device is switched on. If a metal object is present, the device makes a noise. After checking the work, you should press the stop button so as not to waste battery power.
