Metal Detector U-12

About Metal Detector U-12

Metal Detector U-12 is an application which detects the presence of metal nearby by measuring the magnetic field value. Metal Detector U-12 allows to identify any metal object in area, because all metals generate magnetic field which strength can be measured with this app. Detects metal object signals at a range of up to 25 cm. 
Detects hidden electrical wires and metal objects in walls.

You can also use this app as a body scanner. A security scanner to detect metallic objects on people like smartphones, keys, and knives, etc. You can use it in rest rooms and changing rooms to detect hidden cameras.

How it works
:
• Measure magnetic field value using a magnetic sensor that is built into your smartphone
• After running this app if your phone shows high reading then immediately keep it away from everything to set it normal.
• The normal Electromotive force (EMF) field level is about 59μT (micro Tesla) or 590mG (milli gauss); 1μT = 10mG. When any metal object like steel or iron is near, EMF reading will increase with a beef sound.

Attention! Not every model of smartphone has a magnetic field sensor. Metal detector cannot detect gold, silver and coins made of copper.
