Abstract: An apparatus for measuring the specific absorption rate (SAR) of a device (8) which generate electromagnetic fields. The apparatus includes a homogeneous solid spherical test phantom which has the average electrical properties of human tissue and at a defined distance from the surface contains a dipole probe which is positioned in such a way that the derived probe signal is proportional to the average SAR for 1 g or 10 g of tissue. The device to be tested, for example a mobile telephone, is guided past the surface of the phantom and turned until the instrument displays the maximum SAR value of the relevant limit.
