Magnacheck 3D - TangenTial FIEld Strength Meter
A gaussmeter, also known as a magnetometer, is a device used to measure the strength and direction of a magnetic field. Gaussmeters are simple to use and handheld versions are available which can be carried to monitor magnetic fields on-site. The device may also be referred to as an electromagnetic field detector, or EMF detector for short. Baugh and Weedon offer a unique 3D probe which can measure the strength of a field in 3 dimensions (x, y and z).
