FIELD: physics.
SUBSTANCE: invention refers to temperature, hydrostatic pressure, liquid electrical conductivity, water oil content, pH value, oxidation-reduction potential Eh, concentration of various aqueous ion meters, as well as to well electric field testers. Assembly contains immersion probe and terrestrial unit which are borehole cable interconnected. Transmitting multichannel measurement transducer of immersion probe has secondary input to which metal case of probe is connected. Besides, terrestrial unit contains electric field analysis block input of which is connected to output of receiving transducer, and output is connected to secondary input of computing unit.
EFFECT: higher measurement accuracy of external electric field intensity.
