Magnetic Susceptibility Probe HM-100
This probes is designed for measurement of magnetic susceptibility of rocks in borehole profile.
The HM-100 is used for measurement in complex of sedimentary rocks, igneous or metamorphic rocks up to low magnetite rocks. The susceptibility is an excellent indicator of lithology.
The probes response is practically instantaneous (<0.5s).
