Zero Gauss Chamber  

• Measuring point for reproducible and location-independent measuring results used for quality assurance, such as for cross-operational supply chains
• Measurements of residual magnetism on ferromagnetic parts are no longer significantly distorted by the ambient magnetic fields

• Passive shielding, no power consumption and maintenance-free
• Defined measuring point, good access to the measuring room
• Rugged platform design

Measurements of residual magnetism on ferromagnetic parts in the range < 4 A/cm (~ 5 gauss) are typically significantly influenced by the induced earth’s magnetic field. Due to the geometry and permeability of the material, induced magnetic fields can be amplified several times over. Depending of the slim, elongated parts in the earth’s magnetic field (e.g. 0.4 A/cm), the measurement results may fluctuate by up to 4 A/cm at the same measuring point.

Component measurements inside the zero gauss chamber can be repeated at any location, allowing a global quality assurance between customers and suppliers.

The ambient magnetic field, which is greatly reduced by the high shielding factor from the chamber, enables accurate measurements in any orientation. This is particularly relevant for elongated parts and materials with high initial magnetic permeability.
