 These systems enable material in a wide range of geometries to be tested from 0.001 Hz up to 200 kHz with controlled arbitrary waveforms.Several of the AC and DC characterisation systems can be used with the sample under stress (±50 kN) or at a pre-defined temperature (varied from −150 °C to +600 °C using an environmental chamber, laboratory oven or oil bath).High magnification domain observation system uses the longitudinal and polar Kerr effect for dynamic observation of surface domain structures at a maximumum rate of 1825 frames per second and maximum magnetification of 500 times.
