PASI - Model RM1 - Earth Resistivity Meter
From Earth Resistivity
RM1 is a compact versatile earth resistivity meter with 24 bit data acquisition. The console keyboard allows easy and immediate access to all the main functions, even in harsh environmental conditions. Supplied as a bundle with its programming, acquisition and data management software, RM1 not only works in 'stand alone' mode but also remotely, connected to any external PC (Windows 7 or higher). This way, the operator can easily create VES tables and customised measurement sessions, making the most of the guided preparation tools. Compatible with any external energiser (max. 1000V - 1A in the standard version, 5A max. in the upgraded version), RM1 is offered in combination with one or more P-200 (200V - 1A) energizers, which can be connected together in series. Completed with the necessary accessories for electrical tomography is able to realize ERT profiles up to a maximum of 32 el.
Applications:
- Subsoil groundwater prospecting at shallow, medium and great depth.
- Geological stratigraphy
- Studies of salt water contamination in fresh water layers
- Landslide monitoring
- Mineral exploration (sulphides, etc.)
- Archaeological research
