RM1 is a compact versatile earth resistivity meter with 24 bit data acquisition. All parameters in “stand alone” mode can easily be set using the console keyboard, even in harsh environmental conditions; connect the RM1 to your laptop via the dedicated acquisition software, and use the taylor-made measuring session (VES/ERT) to organize your in-field sessions quickly and efficiently. It is recommended, as to exploit its capabilities, to use it in conjunction with one or more P-200 energizers.


water surveys of the subsoil to shallow, medium and great depths
geological stratigraphy, landslide studies, etc.
groundwater contamination by salt water and / or pollutants
subsoil cavities detection
mining (sulphides, etc.)
