描述
The model ZGC zero gauss chamber reduces the environmental magnetic field (Earth field) to near zero inside the chamber. Any gaussmeter probe which is less than 9.4 mm or 0.370″ diameter can be placed inside. The meter is then “zeroed”, which means that it will read zero whenever the probe is subsequently placed in zero field. By using a zero gauss chamber, any offset error is therefore eliminated. The model ZGC is unique in that it contains a degausser (demagnetizer). This is situated between the inner and outer mu-metal shields. When the degauss button is pressed, any accidental magnetization of the chamber, no matter how strong, is erased. Accidental magnetization is a major problem with most zero gauss chambers and it has limited their use. If a magnet comes too close, the chamber will become “permanently” magnetized and will have an internal field that is typically 0.2 to 0.5 gauss. The chamber must then be degaussed because the Earth field is also around 0.5 gauss, so a magnetized zero gauss chamber will not significantly reduce the field.
模型中关村零高斯室减少环境磁场（地磁场）接近零的室内。任何高斯计探头，小于9.4毫米或0.370“直径可以放在里面。米是“零”，这意味着它会读零当探针随后放置在零场。采用一零高斯室，因此任何偏移误差的消除。模型，它包含一个去中关村独特（磁器）。这是位于内部和外部之间的亩金属盾牌。当消磁按钮被按下，任何的室意外磁化，无论多么强大，擦除。偶然的磁化与大多数零高斯室的一个主要问题，这限制了它们的应用。如果一个磁铁太近，商会将成为“永久”磁化，会有一个内部的字段，通常是0.2到0.5高斯。然后室必须消磁因为地球磁场也在0.5高斯，所以磁化零高斯室不会显著降低场。
