Handheld metal detector MD3003B1

Function Features:
1. The operation is simple and convenient, and the user manual is available in both Chinese and English versions.
2、Sensitivity easily detects a large headpin-sized metal object (3.5cm away from the probe plate).
3. The detection area is large, and one complete detection from top to bottom significantly improves work efficiency.
4. Currently, it is the only one in this style with an independent battery under-voltage system, with the yellow indicator light on.
5. The distinctive feature is the dual warning method of sound and light and vibration, which accurately and quickly determines the location of the metal.
6、Has a concealed moisture-proof and adjusts the sensitivity of the hole, less failure, economical and durable.
7、This itemMetal DetectorIt is the most heavily equipped electronic manufacturing plant and security personnel.

It is also the largest export quantity in China, accounting for 45% of the total.
8. At the same time, it has the feature of being extendable in subsequent technologies: it can be equipped with a wireless charging system in the future.

Product Parameters:
Dimensions: Length 415mm * Width 65mm * Height 40mm
Packing Size: 44.5cm * 26.5cm * 52cm
Single total weight: 0.5KG/PCS
Power supply: 6F22ND 9V battery (alkaline battery, rechargeable battery D3003B1 uses 9V battery or rechargeable battery. When installing the battery, open the battery cover, and pay attention to the polarity when installing the battery. Turn on the on/off switch button, and the green light will illuminate. At this time, the detector can work normally. The detector can adjust the sensitivity and detection range until the red light illuminates and there is a continuous alarm sound. Rotate the sensitivity regulator counterclockwise until the red light goes out and the alarm sound disappears. At this time, the detector is in the most suitable sensitivity and detection range.
The handheld detector scans the surface of the object with the detection area at a distance of 10-30 millimeters, moving back and forth continuously.
If there is metal, the detector will emit an alarm sound and the red light will turn on. When the detector remains over a metal object without moving, the detection signal will automatically weaken. Therefore, it is very important to continuously scan back and forth when using the detector.
Usage:
1. Electronic detection inspection at airports, train stations, and harbors
2. Customs, border defense, and security protection department security checks
3. Quality Inspection of the Medical and Food Commerce System
4. Security checks at important locations and sports venues
5. Precious metal detection, such as gold and silver jewelry factories
Performance:
The detector's sensitivity is mainly determined by the size, shape, and composition of the object being detected.
