Gauss Meter 1.12

This app uses the magnetic field sensor on your device to measure magnetic flux density (B) in Gauss or Tesla. FOR INDICATION ONLY. Results depend on your device and its hardware. Your device must have a Magnetic Field Sensor for this app to function. Features include:

Analogue dial to show current reading.
Averaging.
Maximum and minimum values.
Gauss or Tesla units.
4 time constant options. 3 Refresh speeds.
Graph – Shows the time depedence of the magnetic field.
Compass
Ferrous metal detector – sound frequency will change with gauss level.
Autoscale or manual (pinch & pan) Y-Axis.
Calibrate option – If you have a calibrated gauss meter or known magnetic source, you can use this option to calibrate the meter. (However app is still for Indication Only).
