Metal Detectors for Reliable People Screening
Keep entrances safe without slowing operations. Penta Technology Solutions supplies, installs, and supports professional walk‑through and handheld metal detectors for security screening across Sri Lanka.
What is a metal detector used for in security screening?
A security metal detector is used to identify concealed metallic objects on people at entrances or checkpoints. Walk‑through models screen high visitor volumes, while handheld detectors are used for secondary checks.
Why Metal Detectors Matter for Modern Security
Metal detectors are one of the most effective and widely adopted screening tools for controlling access and reducing risk. They help security teams:
Detect
Detect concealed metallic threats early at entry points
Safety
Improve safety at crowded venues and sensitive facilities
Screening
Maintain visitor flow with fast, repeatable screening
Access
Support a professional, controlled access experience
For organisations in Colombo, Kotte, Kandy, Galle, Jaffna, Negombo and beyond, reliable screening is now a baseline expectation for events, schools, workplaces, and public-facing locations.
Metal Detector Types We Provide
Walk‑Through Metal Detectors (WTMD)
Designed for high-throughput entrances, walk-through metal detectors create a screening corridor. They are ideal where you need fast entry + consistent detection.
Common use cases
- Main entrances (offices, hotels, malls, government buildings)
- Event access points (concerts, school functions, exhibitions)
- Staff entrances for factories and warehouses
Key advantages
- Screens large volumes efficiently
- Adjustable sensitivity for different risk levels
- Zone indication helps pinpoint where metal is detected
Handheld Metal Detectors (HHMD)
Handheld detectors are used for secondary screening after a walk-through alert or when screening individuals one-by-one.
Common use cases
- Bag checks and targeted screening
- VIP entry screening
- Mobile security teams and temporary checkpoints
Key advantages
- Quick and precise detection
- Compact, portable, and easy to deploy
- Suitable for indoor and outdoor operations
Specialty Options
Depending on your site, we can also recommend:
- High-sensitivity models for stricter screening environments
- Weather-resistant solutions for semi-outdoor entrances
- Enhanced zone detection for faster secondary checks
Key Features to Expect in Professional Metal Detectors
A reliable screening system should deliver accuracy, speed, and easy day-to-day operation.
Adjustable sensitivity to match your security policy.
Detection zones (single or multi-zone) for faster identification.
Stable performance to reduce unnecessary alarms.
Clear status indicators and audible alerts.
Quick configuration and preset modes.
Simple calibration and routine checks.
Options for compact entrances and high-traffic entry lanes.
Durable construction for frequent use.
Compatibility with queue barriers, entry gates, and access control workflows.
How a Metal Detector Screening Setup Works
- Entry management: Visitors are guided through a defined entry lane.
- Primary screening: Walk‑through detection identifies metallic objects.
- Secondary screening: Handheld scanning confirms and pinpoints items.
- Resolution: Security staff manage permitted items and restrict prohibited objects.
This approach keeps the screening process consistent, professional, and scalable.

Selecting the Right Metal Detector for Your Site
Use this paragraph section to get your website visitors to know you. Consider writing about you or your organization, the products or services you offer, or why you exist. Keep a consistent communication style.
A quick selection guide
- High visitor volume → Walk‑through metal detector + handheld for secondary checks
- Smaller entrances → Compact walk‑through model or handheld-based screening
- Temporary operations → Handheld detectors + portable lane management
- Higher-security sites → Multi-zone + higher sensitivity + stricter screening SOP
What we consider during consultation
- Entrance width and available space
- Peak-hour throughput (people per minute)
- Desired sensitivity (minimising missed detection vs reducing false alarms)
- Indoor vs outdoor exposure
- Staffing plan (how many screeners per lane)

Best Practices for Better Screening Outcomes
To improve accuracy and throughput:
- Use clear signage to reduce confusion at the entrance
- Create a defined lane with barriers (keeps flow smooth)
- Apply a consistent policy on keys, belts, phones, and metal accessories
- Use handheld detectors for quick secondary checks—avoid delays
- Maintain routine checks to ensure stable detector performance
