McOHM-EL

Cost effective system with two functions i.e. conventional resistivity survey and electric logging in on unit

McOHM-EL is a new concept in resistivity meters, as it not only measures conventional resistivity but also a number of borehole parameters can be logged.
The tools supported are normal resistivity, temperature and caliper.
This combination gives the geoengineer greater opportunity to prove his interpretation.
Despite this added flexibility the system has been kept low in cost, thus giving better value to the user.
It incorporates advance feature such a 24 bit Delta Sigma converter, LCD display, high resolution printer and floppy disk for storage.

● Resistivity meter with borehole logging function

● 24 bit Delta-Sigma A/D converter

● High resolution thermal printer

● Floppy Disk storage 720KB/ 1.2MB/ 1.44MB

● High transmitting voltage 400V

● Light weight 8kg
