SA-IIIA Door Frame Metal Detector Archway Metal Scanner (SAFE HI-TEC)
The SA-IIIA is a high-sensitivity digital walkthrough metal detector that utilizes advanced electromagnetic testing and digital processing technology. It offers excellent detection capabilities for both ferrous and non-ferrous metals, as well as the ability to recognize personal items such as coins, keys, and belt buckles. The system can detect a 20mm diameter steel ball at its highest sensitivity level. Its multi-layered overlapping coil design, combined with high-brightness LEDs, provides accurate horizontal positioning of detected metal objects, making it easier for operators to identify the location of the item.
Function: This walkthrough metal detector is ideal for identifying dangerous items like knives, guns, and other concealed metal objects on individuals. It ensures a safe environment in places such as airports, schools, and public events.
Key Features:
1. Intelligent traffic and alarm counters for tracking flow and alarms.
2. Six pinpoint detection zones for accurate localization from head to toe.
3. Advanced broadband detection technology for both ferrous and non-ferrous metals.
4. Adjustable sensitivity from Level 0 to 299, allowing customization for different environments.
5. Shockproof design to reduce false alarms.
6. Sound and light alarm system for clear alerts.
7. Tamper-proof operation with password protection.
8. Adjustable operating frequencies to avoid interference from X-ray machines, radios, and other electrical devices.
9. Distance between two walk-throughs: 0.3 meters at low sensitivity, 0.5 meters at high sensitivity.
10. Safe for pregnant women and those with heart pacemakers.
11. One-year warranty on parts.
Our Service:
Comprehensive training programs for end users and engineers. Free factory training available. One year of free spare parts. Lifetime technical support. We are committed to providing reliable and long-term service to our clients.
