OCTA security detector

1. Product Introduction

This portable safety inspection device is widely used in public places such as airports, stations, shopping malls, schools, and government offices, as well as at large events like concerts and sports competitions. It is primarily designed to detect metal items, including mobile phones, knives, guns, and explosives, in people, packages, and luggage. The device uses a non-contact detection method, allowing for quick and accurate identification of the location and type of metal items, making it an extremely practical safety inspection tool.

Ii. Working principle

The working principle of the handheld metal detector used in security checks is based on electromagnetic induction. When a metal object enters the detection area, it alters the magnetic field inside the detector, generating an induced current that produces sound and light signals to indicate the presence of a metal object. Inside the detector, there is a transmitting coil and a receiving coil. The transmitting coil emits high-frequency electromagnetic waves, which are then received by the receiving coil and converted into electrical signals. The detector converts these signals into audible sounds or visible lights to indicate the detection results.

3. Product features
4. High sensitivity: The handheld metal detector for security checks uses high-sensitivity electromagnetic induction technology, supporting both proximity and sweeping detection methods. It can detect tiny metal items such as blades and needles. This highly sensitive detection technology significantly enhances the accuracy and reliability of the inspection, ensuring effective results.
5. Easy to Use: The handheld metal detector for security checks is simple to operate. It only requires pressing a switch to start the detection process, eliminating the need for complex procedures or specialized training. Ordinary personnel can easily use it. This user-friendly design enhances work efficiency, reduces operational complexity, and enables security personnel to perform their tasks more efficiently.
6. Portable design: This product is small in size, the weight of the whole machine is 200g, can be carried around, convenient to use. This portable design enables security personnel to work more flexibly, not limited by place and environment
7. High reliability: The handheld metal detector for security checks is crafted from high-quality materials and advanced manufacturing techniques, with all circuit components adhered using standard surface mount technology. The device’s casing meets the IP31 protection standard as specified in GB/T 4208-2017, allowing it to withstand drops from a height of 1m on any six sides without malfunctioning. This high-quality design ensures the device remains reliable and accurate over long-term use.
8. Multiple Alarm Methods: This product can trigger alarms through various methods, including sound, vibration, and light. It will immediately stop the alarm once it is at a safe distance from the test object, ensuring the accuracy of the detection results. In noisy environments, it uses sound and light alarms; in quiet settings like examination rooms, it uses vibration and light alarms. This multi-alarm design enables security personnel to promptly identify any anomalies, thereby enhancing the efficiency and accuracy of safety inspections.

6.☆ Built-in 3.7V lithium battery, when the power is low, there is an automatic continuous alarm sound, the indicator light is red when charging, and the indicator light will automatically extinguish after full charge to ensure the safety of charging.

7.☆ Under-voltage warning: The status indicator light automatically turns on red.

8. ☆ Equipped with USB Type-C charging port, which can be used for recycling charging. Standard charging adapter and charging cable are provided.

9.☆ The production process strictly follows the ISO9001 quality management system, and the work is stable and reliable. It is an ideal and reliable safety product to strengthen information security, ensure product production and protect the environment.

Applicable places

At airports, stations, and other public places, handheld metal detectors are used to check passengers for dangerous items such as knives, guns, and explosives, ensuring public safety. In government offices, schools, and other venues, these detectors are used to check for prohibited items like knives and lighters, ensuring the safety of these areas. In factories, warehouses, and other facilities, handheld metal detectors are used to check for metal foreign objects in products, ensuring product quality and safety.
