Dual Induction Conductivity Probe HII-383

The probe HII-383 is designed for measurement of electrical conductivity of rocks in boreholes. High stability and exceptionally wide dynamic range are giving you possibility to carry on precise measurements of conductivity of sand-clay layers and also mineralized water-soaked sands. Thanks to the induction method applied the probes can be used in water filled, dry and plastic cased boreholes. The response is practically instantaneous (<0.5s).
