Mumetal® ZERO GAUSS CHAMBERS
our most popular mumetal® scientific product




Create a low Field lab environment

MuMETAL® Zero Gauss Chambers are used worldwide by many universities, private research companies, national laboratories and companies required to provide evidence of military or consumer regulatory compliance.  Our Zero Gauss Chambers are preferred because they are scientifically engineered chambers fabricated from High Permeability (M) Stress Annealed MuMETAL® alloy and maintain a laboratory workspace or test area of consistent extremely low magnetic field.

Standard Zero Gauss Chambers consist of 3-layers designed to attenuate external low frequency A.C. fields 1,000 to 1,500 times. Zero Gauss Chambers are effective because of layering. When two or more concentrically spaced magnetic shields are used in series (one inside the other) and magnetically isolated, the attenuation of the external field is multiplied. This multiplying effect of successive shields provides substantially greater attenuation of magnetic fields than a single shield of equivalent total wall thickness. Although custom chambers are available in different diameters, lengths, thicknesses and configurations, most applications can be solved with one of our standard models. Each of the three magnetic shield layers consists of a cylinder with one closed end and one open end (access opening). A close-fitting, removable cover is provided on the access opening end. Of all geometric shapes, a cylindrical configuration is one of the most effective for absorbing external magnetic flux lines, thus creating an efficient magnetically shielded finite space.

To achieve the lowest magnetic levels within the chamber and for providing optimum long term stability and uniformity of the internal magnetic field levels, the periodic use of a Degaussing Coil is recommended. We offer both standard and high temperature insulated Degaussing Coils.

Standard stock sizes are available or request a quote for custom configurations produced to spec for your application.
