The SA-IIIC high-sensitivity digital walkthrough metal detector uses advanced electromagnetic testing and digital processing technology to detect both magnetic and non-magnetic metals with high accuracy. It is capable of identifying small personal items such as coins, keys, and belt buckles, making it ideal for high-level security applications.
Key Technology Features
1. Detects even the smallest metal objects like a paper clip, suitable for high-security environments.
2. Equipped with multi-zone high-brightness LED lights and sound alarms for accurate location identification.
3. Combines digital and analog technologies for strong anti-interference capabilities, minimizing false alarms.
4. Offers self-diagnosis and real-time status monitoring, along with visual and audible alarms.
5. Durable outer cover made from high-strength materials that are waterproof, fireproof, corrosion-resistant, and shockproof.
6. Modular design for easy installation and maintenance.
