Gauss Meter
W-FI-10 - Intended to be used for Demagnetization and are calibrated during manufacture in a Homogeneous Field (Helmholtz Coil +/- 10 Gauss).
W-FI-20 - Intended to check residual fields, and are calibrated during manufacture for a Homogeneous Field (Helmholtz Coil +/- 20 Gauss).
W-FI-50 - Intended to check strong residual fields, and are calibrated during manufacture for a Homogeneous Field (Helmholtz Coil +/- 50 Gauss).
