Earth Resistivity Meter: 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. Applications • 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.) • archaeology Methodology • Vertical Electrical Soundings (VES) • Electrical Profiling (EP) • Self Potential (SP) • Induce Polarization (IP) • Electrical Resistivity Tomography (ERT, Electrical Imaging ) •    24-bit Sigma-Delta ADC + oversampling for noise reduction • A.I. (Artificial Intelligence) function with automatic setting of all acquisition parameters (V, I, Te, T0, Ti, etc.) • Standard deviation setting (a) to optimize measurement accuracy and acquisition times •    Internal > 5000 measurements (standard version) • Electrical Resistivity Tomography function (ERT) - 32 el. (optional) •    USB data transfer • Internal battery autonomy: > 1300 continuous measurements (electrical tomography); more than 40h works in SEV mode •    Power supply from external power bank (optional) or PC (via USB) •    Automatic Filtering - oversampling - 50/60 Hz noise removal • Noise reduction with stacking and average of the acquired values •    Autocalibration at start-up • Connects to any external energy source - max.1000V-1A (5A opt.) • Light compact PELI IP 67 case - 270x246x123mm - 2.9kg PASI S.R.L. — Via Galliari 5/E — 10125 Torino tel. +39 011 6507033—e-mail:
