We are professional manufacturer of geophysical survey and geophysical prospecting, such as geophysical instrument, resistivity meter, resistivity IP and SP system, resistivity, IP, SP, TEM survey, magnetometer, seismograph, gravity meter, proton magnetometer, drill, and element analyzer.
Features and application:
Features and application:
1. With the variation of apparent resistivity, it is widely used for searching underground water and non-metal ores (quartz mine, calcite mine, coal ore and talc ore etc), which also plays an important role in sides as ores prospecting and water detect etc.
2. Micro-PC controlled, resistivity value read directly, multiple arrays, data protection when power-down.
3. It is applied for ground and sap' s electrical prospecting method like vertical electrical sounding (VES), electro-profile method, IP charge method and SP method etc. The applied field includes hydrology, environment, engineering prospecting, metal and non-metal mineral source detect etc.
