Overview
The AR924M Underground Metal Detector is a professional detection equipment of the SMART SENSOR brand. It uses the principle of electromagnetic induction to generate a rapidly changing magnetic field through the coil, which induces eddy currents inside the metal object and triggers the detector to sound. The product uses LCD display and audio prompt, which is specially used to detect buried metal objects. It can determine the position, size and type of metal objects by processing induction signals.
Features
1. Adopt LCD display and audio prompts to facilitate users' intuitive access to detection results.
2. It has the function of distinguishing between ferrous and non-ferrous metals, allowing it to distinguish between different types of metals.
3. Sensitivity adjustment function to adapt to different detection environment requirements.
4. Built-in searchlight to improve the convenience of use in low-light environments.
5. Support external headphone jack to provide private auditory feedback.
6. It has a low power prompt function to ensure the safe use of the equipment.
7. The detection distance can reach 1.8 meters (for 50cm * 50cm * 1.2cm Aluminum Panel), and the detection performance is strong.
8. Using 7.4V 2000mA lithium battery, Working time up to 6-10 hours, excellent battery life.
Principle
The AR924M underground metal detector works based on the principle of electromagnetic induction. The detection coil emits electromagnetic signals. When the signal encounters an underground metal object, eddy currents are induced inside the metal. The magnetic field generated by eddy currents in turn affects the original magnetic field. The Control Unit processes these induced signals and prompts the user about the metal object through LCD display and sound.
Applications
Archaeological research, treasure hunts and treasure hunting activities, metal detection and exploration, safety inspections and dangerous goods removal, pipeline and cable laying and maintenance
Steps
1. Turn on the power of the device and check the battery power.
2. Adjust Sensitivity settings as needed.
3. Select the detection mode (equilibrate or recognition mode).
4. Slowly move the detection coil close to the ground for scanning.
5. Observe the LCD display or listen to audio prompts to identify metal objects.
6. After finding the target, locate it accurately and record the location.
Notice
Do not use or store the device in an extreme temperature environment.
• Avoid long-term exposure of equipment to humid or corrosive environments.
• Make sure the battery is fully charged before use, and charge it in time when it is low.
• Keep the coil parallel to the ground during detection to avoid rapid movement.
• In safety inspection and dangerous goods removal applications, it is necessary to operate by professionals.
