Magnetometer and Field Indicator

Polarity indicator and remanence with needle calibrated in Gauss. Range + / – 20 Gauss.

Western Instruments manufactures 4 models of Disposable Field Indicators, which provide readings in Gauss;

1.  W-FI-10 – Intended to be used for Demagnetization and are calibrated during manufacture in a Homogeneous Field (Helmholtz Coil +/- 10 Gauss).

2.  W-FI-20 – Intended to check residual fields, and are calibrated during manufacture for a Homogeneous Field (Helmholtz Coil +/- 20 Gauss).

3.  W-FI-50 – Intended to check strong residual fields, and are calibrated during manufacture for a Homogeneous Field (Helmholtz Coil +/- 50 Gauss).

4.  W-FI-100 – Intended to check very strong residual fields, and are calibrated during manufacture for a Homogeneous Field (Helmholtz Coil +/- 100 Gauss).
