technical data:index number: yt-73138ean: 5906083069192brand: yatometal detection: yesdetection of wooden profiles: yesdetection of live wires: yesdetection depth of ferromagnetic metals: 120 mmdetection depth of non-ferrous metals: 80 mmdetection depth of live wires: 50 mmdetection depth of wooden profiles: 38 mmprofessional wire detector profile detector and moisture meter in one. The yt-73138 allows you to detect in walls or drywall:live wires up to 50 mmferromagnetic metals up to 120 mmnon-ferrous metals (e.g. Copper pipes) up to 80 mmwooden structural elements precisely up to 20 mm roughly up to 38 mmthe built-in wood and building materials moisture meter allows for:measurement to a depth of up to 8 mmwood moisture measurement in the range of 5-50%measurement of building materials moisture in the range of 1.5-33%using the yato yt-73138 4-in-1 detector and meter significantly speeds up work increases safety and minimizes the risk of accidental damage to electrical or plumbing installations located under plaster. Thanks to it you can among other things safely drill a hole or find a place to screw a screw into a wooden or metal profile hidden under drywall. The built-in moisture meter will allow among other things determining the level of plaster moisture in thermal bridges as well as checking the moisture content of firewood.a large and legible display with led backlight informs us about:selected functionsignal strength [%]distance from the searched metal element [cm]central location relative to the sensoradditional functions and equipment:audible signal and three signaling diodes green / orange / red which additionally indicate the detection of the searched material.adjustable detection power for live wires and metal elementsautomatic shut-off after 5 minutes of inactivityon the underside of the detector there are inserts made of soft material which protect the housing from scratching when in contact with the surface.device cover made of durable material**photos they serve an illustrative purpose.
