Magnetometer 25/1-0-1 Gauss Handheld 323 The main goal of thisPOCKET MAGNETOMETERS DUAL PURPOSE, TWO COLOR SCALE makes the Model 25 Magnetometer more useful. The upper Black scale (the one more usually used) reads directly in gauss of a uniform magnetic field oriented parallel with the centerline of the instrument scale. The lower Red scale is used in determining the magnitude and direction of an unknown magnetic field by merely orienting the instrument for maximum reading. When shown in the Red scale, at such a
