Overview
The AR934 Handheld metal detector uses the principle of electromagnetic induction to generate a rapidly changing magnetic field through an alternating current coil, inducing eddy currents inside metal objects and generating a reverse magnetic field, which triggers the detector to issue an alarm sound. The product is suitable for a variety of security inspection scenarios and helps to quickly detect hidden metal objects.
Features
1. Provide a variety of detection prompt methods for buzzer alarm, vibration and earphone sound alarm
2. With LED light alarm prompt function
3. Support low power prompt function
4. Sensitivity adjustment function
5. Equipped with external headphone jack
6. Lightweight design, Net weight only 410g
7. Continuous Operating Time up to 6-10 hours
Principle
Handheld metal detectors use the principle of electromagnetic induction to generate a rapidly changing magnetic field through a coil of alternating current. When a magnetic field acts on a metal object, it induces eddy currents inside the metal, which in turn generate a new magnetic field, which in turn affects the original magnetic field, triggering the detector to issue an alarm sound.
Applications
Security, Airport Security, Station Security, Event Security, Industrial Inspection, Food processing, Wood processing, Spinning & weaving
Steps
1. Install a 9V battery to power the device
2. Turn on the power switch to start the detector
3. Adjust Sensitivity Settings as Needed
4. Move the detector close to the area to be detected slowly
5. When metal is detected, the device will sound an alarm via beep, vibration, or LED light
6. Can be connected to earphones for mute detection
7. Turn off the power after use
Notice
Do not use in high temperature, humidity or strong electromagnetic interference environment
• Avoid strong impacts or drops to the detector
• Regularly check the battery level and replace the battery in time
• Keep the detector at an appropriate distance from the detected object when in use
• Please use a dry soft cloth to wipe when cleaning, avoid using chemical solvents
• Please remove the battery when not in use for a long time
