Phase Angle—Page 1
For a brief overview of what phase-angle is and its importance to the art and science of
metal detection, see page 278. As a general rule, the following phase angles are
representative of the following types of contaminants and non-contaminated products.
Degrees Contaminant or non-contaminated product
+ 130 Metallic (ferrous) conductive contaminants, such as iron.
+ 90 Dry, non-conductive products, such as cereals and grains.
+ 65 Non-ferrous metallic contaminants, such as brass and aluminum.
+ 20–30 Metallic contaminants, such as 300-series stainless steel.
0 Wet, conductive products, such as fresh meats and breads.
