MicroSense ET7 磁力计

"MicroSense offers true torque magnetometers both as an option to the EV Vibrating Sample Magnetometer (VSM) systems and as a standalone system (ET7, ET9 and ET11 systems).","The most typical configuration, the ET9, can reach fields up to 28 kOe at a sample space of 10 mm with the standard 50 mm pole faces and above 31 kOe with the optional 25 mm pole faces. This is 10 kOe more than can be obtained with vector based torque magnetometers using a magnet that is 3 times the size (weight) of the ET9 magnet. Competing vector based systems using a magnet similar in size to the ET9 system can only reach a maximum field of 12.5 kOe, much to low for many modern materials.","If needed an even higher field can be obtained using special alloy pole faces. Alternatively, with the ET11 system fields above 34 kOe can be reached.","The Torque magnetometer model can measure solid, bulk, and thin film samples and is supplied with sample holders for all these types of samples. The excellent real world low noise performance make this torque magnetometer the perfect choice for samples with a low torque.","Due to a highly efficient magnet power supply design, no water cooling is needed for the electronics. Because of this, the Torque magnetometer can operate at a medium duty cycle or at low fields without the need for a water chiller. For many measurements this eliminates a source of acoustic noise from the lab environment. Also, removing water cooling from high power electronics makes this system inherently safer than water cooled power supply designs.","Included with the system are all the options needed to run including the EasyVSM software which is easy to use for simple measurements yet powerful enough for the most complicated measurements."
