• Caution : The detection depth and accuracy of PQWT-QT28 are easily affected by factors such as the ambient temperature and humidity, the texture of the wall, the density of the wall, the moisture content of the wall, the humidity of the stud, the width of the stud, and the curvature of the stud edge, etc. Do not use thisdetector in strong electromagnetic/magnetic fields, such as, electric fan, motor, high-power devices, etc.
• PQWT-QT28 can scan the following materials: Dry wall, plywood, hardwood flooring, coated wood wall, wallpaper.
• PQWT-QT28 cannot scan the following materials: Carpets, tiles, metal walls, cement wall.
