Stud Finder Wall Detector, Electronic Wood & Metal Sensor, 20mm Deep Scan Tool for Home DIY Renovation with Sound Alarm

Product Selling Points:

1.100% brand new high-quality products.

2. Made of high-quality materials, durable and practical.

3. Suitable for use in indoor decoration structures, it can detect the position of metal and wood inside walls. When metal and wood are sensed, the instrument will flash and emit sound prompts, and can also detect other foreign objects inside the same object.

4. Ergonomic design, comfortable to use.

5. Search for the edges of wood or metal rivets, with a depth of up to 3/4 inch (20 millimeters).

Test sampling:

Place the instrument on the surface being tested, press the power switch, and the first red and green indicator lights will turn on, emitting a "drip" sound. Then the red indicator light will turn off, indicating success When sampling, the first red indicator light stays on and emits a short "beep" sound, indicating that the sampling is unsuccessful, there is interference, or the tested object exceeds the built-in allowable value

Test operation:

After successful sampling, do not release the power switch and move along the tested surface. When the instrument senses a foreign object, the red indicator lights will start to light up in sequence. When the LED is fully lit and emits a "beep" sound, make a mark with a pencil and release the power switch

Place the instrument in the opposite direction of the surface for sampling, approach the marked position, and when the instrument senses a foreign object, the red indicator lights will start to light up in sequence. When the LED is fully lit and emits a "beep" sound, make a mark with a pencil and release the power switch

Repeat the test several times, and if all alarms are triggered There may be support columns (foreign objects) between the middle areas

When there is no metal or other foreign object below, it will not flash or make any sound. To ensure accurate test results, it can be tested multiple times

Main parameters:

Power supply: 6F22 type 9V battery (this product does not come with a battery)

Product size: 145x62x25mm

Product weight: approximately 71g (without battery)

This instrument is designed based on the principle that changes in material density below the surface of the object being detected cause a change in detector frequency. The maximum detection depth is 19mm below a uniform object surface, with a detection range error of 3mm. The range of the detected object cannot be less than 1200mm2
