Main Characteristic:
1. By utilizing the apparent resistivity parameters, it is widely used in hydrology, environmental protection, engineering geophysical exploration, metal and non-metal mineral resources exploration.
2. Microcomputer controlled, direct-reading resistivity, various electrode arranging mode, data protection against power-failure.
3. This instrument applies to Electrical Prospecting such as Vertical Electrical Sounding, Electrical Profiling, Charging Method and Spontaneous Potential Method, etc. on ground and in trench.
