The SA-IIIC high-sensitivity digital walk-through metal detector utilizes advanced electromagnetic testing and digital processing technology, offering excellent detection capabilities for both magnetic and non-magnetic metals. It also provides accurate recognition of personal items such as coins, keys, belt buckles, and more.
Key Technology Features
1. Capable of detecting small metal objects like a paper clip, ideal for high-level security checks.
2. Equipped with multi-zone high-brightness LED lights to indicate the exact location of detected items along with sound alarms.
3. Combines digital and analog technologies for strong anti-interference performance, minimizing false alarms.
4. Strong self-diagnosis capability, real-time status monitoring, and visual and audible alarms for errors.
5. Outer casing made from high-strength materials, offering waterproof, fireproof, corrosion-resistant, and shockproof properties.
6. Modular design for easy installation and maintenance.
