RMT300-1000型标准磁体

用标准磁体可对高斯计的探头进行校准。Magnetic Instrumentation公司的标准磁体采用高性能的永磁材料制造，多年来在国际市场上一直享有盛誉。这些高品质的产品具有长期的稳定性，而且提供横向和轴向两类的标准磁体。此外，16580型零高斯腔可以提供一个标准的零磁场。

横向的标准磁体可以稳定的使用在0-50℃之间，温度系数为-0.02%/℃，因为温度系数为负数，所以当温度上升的时候，磁场强度下降。标准磁体的外壳具有高磁导率，它能有效的防护外界磁场。　　LakeShore提供的标准磁体从100高斯到20,000高斯，其中用的最多的是1,000高斯。大多数标准磁体的精确度为±0.5%，200高斯以下的标准磁体精度为±1%。标准磁体的间隙为0.15cm，当然也可以做到0.1cm到0.64cm，最稳定的空隙面积大约在0.5平方英寸。

轴向标准磁体采用铝镍钴合金制成，用以保证它的稳定度和饱和度，它的温度系数与横向标准磁体的相同。当高斯计或磁通计的探头插入标准磁体的孔径的时候，可以测出3个最大值，一是探头将要进入磁体时，二是探头到达中心时，三是探头离开磁体时。最大值在磁体的中心，应用此数值进行标定。
