10pcs Metal Detector Ts79 Three in One Wall Detector Wooden Column Voltage Density Detection Electronics

Product advantages:It is suitable for indoor decoration structure. It can detect the position of metal, wood and electrified circuit in the wall separately. When metal, wood and electrified circuit are sensed, the instrument will have analog strip display and sound prompt

 

Product technical characteristics:

This instrument is designed based on the principle that the change of material density below the surface of the object to be detected will cause the change of detector frequency. It can test metal, wood and electric circuit separately, and the detection depth is under the surface of a uniform object:

Wood 30 × 30mm：≤18mm

Metal detection depth: iron pipe Φ 25mm≤30mm

AC wire: 90~250V ≤ 50mm

 

General features of products:

Test sampling:

Place the instrument on the surface of the object to be measured, gently press the power switch next to it for 2 seconds to start the machine, press the middle selection key to select the type of object to be measured, and then press the power key to sample, making a "drop" sound, indicating successful sampling

Test operation:

After successful sampling, do not release the power switch and move along the surface to be measured. When the instrument senses foreign matters, the analog bars on the LCD screen begin to display in turn. When the analog bars are fully lit and make a "dripping" sound, make a mark with a pencil and release the power switch

Place the instrument in the opposite direction of the surface for sampling, and approach the marking position. When the instrument senses foreign matters, the analog strips on the LCD screen begin to display in turn. When the analog strips are fully lit and make a "dripping" sound, make a mark with a pencil and release the power switch

Repeat the test several times. If the alarm is given, the object under test may be between the middle areas

When there is no corresponding test object below, it will not display or make a sound. For the sake of accurate test results, you can test several times

Power supply: 6F22 9V battery
