120mm Deep Metal Detector Wall Scanner - Rebar, Copper Pipe & AC Wire Detector with LCD Backlight | Professional Construction Tool for Home Renovation, Site Work | Perfect for Adults & DIY Enthusiasts | Detect Hidden Objects Behind Walls, Wood & Concrete Surfaces

This measuring tool is used to detect metals (ferrous metals and non-ferrous metals, such as steel bars), joists and live wires/conductors in walls, ceilings and floors. Walls include: ceilings, floors, conventional concrete, ceramic tiles, and wood. Maximum scanning depth: Black metal: 120mm Non-ferrous metal (copper) 100mm Alternating Current (AC): 50mm Copper conductor (live) (4mm2) 50mm Wood: 20mm Turn off automatically after appointment: 5 minutes. Working humidity range: metal: 0-85% RH wood: 0-60% RH Copper conductor (live): 0-30% RH Working temperature: -10+50 Storage temperature: -20+70 Battery: 1x9V (not included) Approximate working life: 6h Measuring object Detection depth (Max.) Depth accuracy: Rebar/copper pipe 20 8cm/6cm ±2cm It can be seen that the depth accuracy is only the data of the steel bar corresponding to the diameter as the measured object, and the accuracy is only that the actual detection depth is not greater than 8cm. 16 7cm/6cm 12 6 cm/5 cm 6 5 cm/5 cm Firewire/Cable 5 cm Detection conditions: air. wood Wooden beam 2 cm Test conditions: different wood, dry gypsum board surface.
