- Model 16GL-N - Earth Resistivity Meter

From

0

Last release of a very popular family of earth resistivity meters, this 16 bits geoelectrical instrument represents a really performing and affordable solution for Vertical Electrical Soundings at medium and great depth. Reliable and lightweight, 16GL-N is characterized by really first-rate performances, even if it remains extremely easy to use. The possibility to download data through USB enables a quick interpretation with the data inversion software. It is recommended, as to exploit its capabilities, to use it in conjunction with one or more P-100-N rechargeable accumulators.
