Magnetic Field Detector

Use your cell phone as a magnetic field detector to measure EMF.

Turns your cell phone into a real metal detector .

Metal Detector allows to identify any metal object in area, because all metals generate magnetic field which strength can be measured with this tool.Metal detector meter in the app can also be used as EMF Meter.

The magnetic field level(EMF) in nature is about 30~60µT(microtesla) or 300~600mG(milligauss) 1µT = 10mG.If there is any metal in the area, the strength of the magnetic field should increase.

* If the phone do not have a magnetic sensor, this app will not work. This is mobile phone / touch pad design limitation, not software problem *

Note: Mobile phone sensor can only detect DC type magnetic field, that is the earth magnetic field. When measuring power line magnetic field ( for example, 50 / 60 Hz AC) , the result is not accurate, or even no reading at all. This app is for daily uses only, please use professional instrument for accurate measurement.
