Description
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.
模型中關村零高斯室減少環境磁場（地磁場）接近零的室內。任何高斯計探頭，小于9.4毫米或0.370“直徑可以放在里面。米是“零”，這意味著它會讀零當探針隨后放置在零場。采用一零高斯室，因此任何偏移誤差的消除。模型，它包含一個去中關村獨特（磁器）。這是位于內部和外部之間的畝金屬盾牌。當消磁按鈕被按下，任何的室意外磁化，無論多么強大，擦除。偶然的磁化與大多數零高斯室的一個主要問題，這限制了它們的應用。如果一個磁鐵太近，商會將成為“永久”磁化，會有一個內部的字段，通常是0.2到0.5高斯。然后室必須消磁因為地球磁場也在0.5高斯，所以磁化零高斯室不會顯著降低場。
