3 in 1 Stud Finder Wire Metal Wood Detectors AC Wire Detect Wall Scanner Finder with LCD Display

Product advantages:It is suitable for use in interior decoration structures. It can detect the position of metal, wood, and live circuits in the wall respectively. When metal, wood, and live circuits are sensed, the instrument will have an analog bar display and a sound prompt. Product technical features: This instrument is designed using the principle that the change of the density of the substance below the surface of the detected object causes the frequency of the detector to change. It can test metal, wood, and charged circuits separately. The maximum 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 Specifications: *Product Name:Metal Detector *Material:ABS *Size:155*72*28mm Package Content: 1 * detector (delivery does not include 6F22 type 9V battery) • 3 in 1 Detection. With automatic calibration for easy and precise detection, there are three modes to select : wood studs, metal objects (rebar, studs and steel/copper pipes) and live wiring. • Accurate Detector Technology. This stud finder can locate center of wood studs up to 3/4-Inch (18 mm) deep, metal studs up to 11/5-Inches (30 mm) deep, Wire Warning detection indicates the presence of live wire up to 2". • High Efficiency. The easy-to-read LCD screen accurately displays what type of stud you are looking for as well as its position and the battery status of the device. • Easy to use. Only two buttons ,first select the probe type ,then just press and hold the side button and scan horizontally across the object surface. Auto power off without any operation after 60 seconds . • Place the instrument on the surface of the object to be measured, gently press the power switch next to it for 2 seconds to turn it on, press the select button in the middle, select the object category to be measured, and press the power button to sample, making a "dripping" sound, indicating that the sampling is successful • After successful sampling, do not release the power switch, move along the measured surface, when the instrument senses a foreign object, the analog bar of the LCD screen starts to display in sequence. When the analog bar is fully bright and emits a "dripping" sound, mark with a pencil and release the power switch. • Place the instrument on the surface to sample in the opposite direction and approach the marked position. When the instrument senses a foreign object, the analog strip of the LCD screen starts to display in sequence. When the analog strip is fully bright and emits a "dripping" sound, mark it with a pencil and release the power switch. • Repeat the test several times, if an alarm is raised. That is, between the areas below there may be the object under test,When there is no corresponding test object below, it will not display or sound. For accurate test results, you can test several times.
