Highly sensitive easy-to-use handheld metal detector

Handheld metal detectors, also known as handheld metal detectors, are devices that are quite commonly used in the security field today. In addition, handheld metal detectors are also used in archeology and rare metal mining.

What is a handheld metal detector?

This is a device used to detect metals. Even if the metal is carefully hidden in the body or hidden deep underground, it will still be detected by the detector. Users just need to use their hand to detect metal around the suspected area. If there is metal, the device will emit a signal.

Principle of operation

Handheld metal detectors operate on the principle of receiving and transmitting electromagnetic waves. When there is no metal nearby, the device will automatically receive and emit electromagnetic waves. However, when metal is detected nearby, the current induced from the metal will cause the receiver wire to deviate from the field, thereby causing the metal detector to emit a signal that can be sound or vibration to signal.

The sensitivity and distance of metal detection will depend on the device’s transceiver. If the transceiver coil is complex and has a superior wave detection mode, it will have high sensitivity and detect metals at long distances. That’s why metal detectors have many different prices. Depending on usage needs, users choose the appropriate product.

Application of handheld metal detector

Metal detectors are used in many different fields related to security.

Airport security:

At the airport, security is an important issue, so supporting equipment such as security cameras, security detectors, conveyor belts, metal detectors, etc. are indispensable after passengers pass through the security gate. When luggage passes through the conveyor belt, security staff will use metal detectors to scan around the passenger to make sure there is no metal left on the passenger’s body (weapons, cutlery, etc.)

Archeology and mining:

Archaeologists or miners use metal detectors to detect rare metals underground. The machine will emit a signal if the ground has metal underneath. The detection distance for metal objects can be up to 2m from the ground.

Army:

Military agencies use metal detectors to detect wartime bombs and mines underground.

Political security:

National political and administrative agencies use metal detectors to control entrance security and prevent terrorism. Political agencies are places where politicians and high-ranking officials often visit, so security is very strict. Handheld metal detectors help control and ensure interior security.

Education:

Cheating tricks in exams are becoming increasingly sophisticated, so tightening measures are necessary. The exam proctor will control candidates entering the exam room using a handheld metal detector. If candidates use phones, USBs, or other electronic devices, they will be detected.

Clothing industry:

In the export garment industry, metal detectors are often used to check if needle tips are left in the finished product.

Are handheld metal detectors harmful?

There is an issue that users often wonder about when using the product: Is a handheld metal detector harmful?

The answer is: metal detectors operate using electromagnetic waves, but the amount of electromagnetic waves is very small, so the harmful effects of manual metal detectors are absolutely zero. Therefore, users can use it with peace of mind.
