UNI-T UT387E Wall Detector Steel Wire Water Pipe Metal Detector with Wall Detection Function This is a kind of fine quality digital wall detector, a metal wood stem center detector with detecting metal and electric wires functions. Multifunctional wall detector, metal detection, wood detection, wire detection, accurate detection, wide ranges of applications. The wall detector can detect metal, wood beams and live cables inside the walls, ceilings and floors (referred to walls, ceilings, floors for conventional concrete, tiles, wood panels, etc.). Features: Multifunctional wall detector, metal detection, wood detection, wire detection, accurate detection, wide ranges of applications. LCD screen design, accurate positioning, intuitive display, simple operation. Five-in-one detection mode, for detecting wood panels, plasterboard-type material wall within the center of the wood stalk, metal location and live wires, and with AC warning function. There are two gears to detect wood, 0.79in.(20mm) and 1.5in.(38mm), you can adjust it according to your demands. It can be used to detect metal pipe, the wall thickness is within 3.94 inches (100 mm). And also can be used to detect live wire inside walls, and the wall thickness is within 1.97 inches (50 mm). Applicable scenarios, the wall detector can detect metal, wood beams and live cables inside the walls, ceilings and floors (referred to walls, ceilings, floors for conventional concrete, tiles, wood panels, etc.).
