JCH-2 10~10000×10-4(SI)range two coil system Magnetic
Susceptibility with 5%F.S resolution
Description
The JCH-2 magnetic susceptibility tool is typically used in mining,
geotechnical, and lithology applications. All electronic circuitry
resides in a high strength non-magnetic enclosure. The operating
frequency is chosen to be sufficiently low to avoid interference
from rock conductivities and the circuitry is temperature
compensated to minimize thermally induced drift.
The extended range is designed for measurements in complex igneous
or metamorphic rocks up to high magnetite rocks. This extended
range has been chosen so as to identify layers containing magnetite
(0.005 – 100%). The main use of the probe is for prospection on
deposits of Fe minerals – magnetite, pyrite and hematite. These
data are to be used for quantitative interpretation of the magnetic
components in the rocks and estimation of the thickness of layers.
