The SA-IIIC high-sensitivity digital walk-through metal detector uses advanced electromagnetic testing and digital signal processing technology to detect both magnetic and non-magnetic metals. It is capable of identifying small personal items such as coins, keys, belt buckles, and more with high accuracy.
Â
Key Technology Features:
 1. Detects even the smallest metal objects like paper clips, ideal for high-level security checks.
2. Equipped with multi-zone high-brightness LED lights and sound alarms for precise location indication.
3. Combines digital and analog technologies for strong anti-interference capabilities, minimizing false alarms.
4. Includes self-diagnosis functions, real-time status monitoring, and visual/audio alarms for errors.
5. Durable outer cover made of high-strength material that is waterproof, fireproof, corrosion-resistant, and shockproof.
6. Modular design for easy installation and maintenance.
