EARTH RESISTIVITY METER RM1

Product catalog summary
Main Features
  • The RM1 Earth Resistivity Meter features a 24-bit Sigma-Delta ADC with oversampling for noise reduction, offering high resolution measurements of 2nV and 1nA.
  • It includes an AI function for automatic parameter settings and a standard deviation setting to optimize accuracy and acquisition times.
  • The device can store over 5000 measurements and supports Electrical Resistivity Tomography (ERT) with 32 electrodes as an optional feature.
  • Data transfer is facilitated via USB, and the internal battery supports over 1300 continuous measurements or more than 40 hours in SEV mode.
  • It is housed in a compact, lightweight PELI IP 67 case, making it suitable for harsh environments.
Methodology
  • The RM1 supports various methodologies including Vertical Electrical Soundings (VES), Electrical Profiling (EP), Self Potential (SP), Induced Polarization (IP), and Electrical Resistivity Tomography (ERT).
Applications
  • It is applicable in water surveys, geological stratigraphy, landslide studies, groundwater contamination detection, subsoil cavity detection, mining, and archaeology.
Technical Specifications
  • The RM1 features a high-resolution 24-bit SigmaDelta ADC for both current and potential circuits, with galvanic insulation and high noise rejection capabilities.
  • The device supports a maximum measurable current of 5A and a maximum measurable voltage of +/-250 V.
  • It operates in stand-alone mode or can be connected to a PC via USB, with a graphical LCD display for ease of use.
  • The RM1 is compatible with external energizers up to 1000V-1A, with an optional 5A capability.
Recommended Configurations
  • Several configurations are available, ranging from systems with 2xP200 energizers for 600m AB distance to systems with 4xP200 energizers for 2000m AB distance.
  • Each configuration includes necessary accessories such as cable reels, electrodes, and mallets.
PASI P-200 Energizer
  • The P200 energizer is designed to complement the RM1, providing an output voltage from 20-200 V and a current of 1000 mA.
  • It features electronic protection against overload and short circuits, and can be connected in series for increased voltage output.

EARTH RESISTIVITY METER RM1-1

Earth Resistivity Meter: RM1www.pasisrl.it 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: [email protected]
