The Hong Kong CEMAR AR934 Handheld Metal Detector is a portable device specifically designed for accurate metal object detection, suitable for rapid inspection in multiple scenarios. Featuring a lightweight structure design, the device weighs under 500 grams with ergonomic grip design, allowing single-hand operation for hours without fatigue, ideal for extended working requirements.
Equipped with high-sensitivity detection modules, the device effectively identifies various common metal materials including iron, aluminum, copper, and stainless steel. The rotary sensitivity adjustment enables users to flexibly modify detection intensity according to environmental interference, achieving multi-level detection from delicate jewelry to large metal objects. Upon detection, the device provides instant feedback through dual alert systems: synchronized LED illumination and buzzer activation ensure reliable signal recognition even in noisy environments.
The AR934 incorporates low-power circuit technology, powered by 2 standard AA batteries with over 30 hours of continuous operation. The anti-misoperation switch design effectively prevents accidental activation, while IP54-rated protection ensures reliable performance in various indoor/outdoor environments. Specially optimized non-slip grip and adjustable wrist strap enhance secure handling in humid conditions.
Key application fields include:
- Public security inspection: Rapid screening of prohibited metal items
- Industrial quality control: Locating residual metal fragments or missing components
- Archaeological exploration: Assisting in identifying shallow-buried metal artifacts
- Daily anti-loss use: Retrieving small metal objects like keys or jewelry
This device emphasizes practical functionality through its three-stage working indicator (standby/detecting/alarm), automatic power-off function after 5 minutes of inactivity, and optional silent vibration mode for discreet operation. The modular structure design facilitates convenient maintenance and component replacement, ensuring long-term service reliability.
