All of this equipment can be surface induced polarization measurement device, resistance measurement, can also be continuously stimulated wells and borehole electrical logging induced polarization measurements, to my company's DUM-2 high-density electrode resistivity meter with automatic converter, also for high-density resistivity measurements. This instrument features such a machine, better than other similar instruments.
Features and functions:
1. The use of signal enhancement techniques and digital filtering, anti-interference ability, high measurement accuracy.
2 automatic natural potential, drift and electrode polarization compensation.
3 to receive part of a transient overvoltage input protection.
4 large LCD display: character dialogue, not only a display of all measured parameters, and observed curves can be displayed, making the measurement results
Intuitive to understand.
5 multi-parameter measurement: measure and store natural potential, a potential supply current (external control mode), depending on the resistivity, half-bad, the tired
And the deviation increases, and so on.
6 power-down protection: power-down data can not afford to function, can store 1MB of data and long-term preservation.
7. Sealed structure, waterproof, dust-proof, long life and other advantages.
