I have used two different Gauss meters to measure the same NdFeB rare earth N45 (45 MGOe) disc magnet (D28X6mm), with a Residual Induction (Br) of 1320-1380 mT. The first is a Dr. Steingroever GmbH FH51 Gauss meter. It would take readings of up to approximately 1.2 Tesla (12,000 Gauss) The other was a DC Magnetometer from AlphaLab (I think this is the right model, as the one I have must be an old model as it's not shown). This one will only take readings of up approximately 0.35 Tesla (3,500 Gauss) So my questions is why the different readings? Are they measuring the same property of the magnet and is there a standard method for recording such measurements? Thank you.
