 a handheld metal detector is a kind of metal detector, because use the name for the way in hand, it is mainly used for factory anti-theft, security checks and test anti-cheating, relative to security, hand-held metal detector is more accurate. Through the electromagnetic induction of metal objects and alarm, alarm mainly through sound and light, vibration, or through headphones.


手持金属探测器


Handheld metal detectors are designed to detect metal objects carried by people or objects. It can detect weapons, explosives or small pieces of metal in packages, luggage, letters, fabrics and other items carried by people. The special appearance of its sensitive surface makes it easy to operate. Better than ring sensor type hand probe. Ultra high sensitivity for special applications. Such as prisons, chip factories, archaeological research, hospitals and so on.


Hand-held metal detector (palm handheld metal detectors, import metal detectors search hand agent) is used to check the location of the person carrying metal, also can be used with metal detector door, when the 'security' alarm found metal objects, using a handheld metal detectors can be found in possession of the accurate position of the metal items. The metal detector USES a rectangular detection head, the detection area is 12 centimeters long.


Before use, first open the battery cover plate on the back of the instrument and load the battery. This instrument USES 9V laminated battery, please note that the nominal voltage on the battery must be 9V, other voltages must not be substituted.


The power consumption of this instrument is very low, and each newly installed battery can work for about 50 hours accumulatively. When the battery power drops to 10%, the instrument will not work properly, and the speaker will make a intermittent sound, indicating that we must replace the battery.

When in use, the security personnel hold the handle with their hands, press the start button with their thumb, and then release it. The signal light of the instrument will start flashing, and the horn will give out a very slight buzzer, indicating that the instrument has entered the working state. Workers hold the device and scan it back and forth across the subject's surface. If there is a metal object, the device will make a sound. After checking the work, you should press the stop button to avoid wasting battery power.


How to distinguish the size of the metal physiology research shows that people's hearing is insensitive to the change of volume (logarithmic relationship), and is more sensitive to the change of tone (linear relationship), the instrument according to the above situation, with the tone of the discretion to determine the size of the metal objects, the advantage of this is different from other similar products, it can make us more correctly distinguish the different size of metal objects.


When the probe of the instrument sweeps over the human body (object), if it makes a low sound, and the sound will gradually disappear after the probe stays above the sound, we can judge it is a very small metal, such as belt buckle, zipper, etc. If the sound is sharp and the sound is continuous even when the probe is stationary, it must be a large piece of metal, such as a dagger or pistol. Dimensions: 41(L) X 8.5(W) X 4.5(H)cm
