Main features
1. Portable: the weight is no more than 1Kg, easy to carry, which is the lightest high density IP resistivity prospector at present.
2. High transmitting voltage, maximum is 380V, which is enough to drive IP &resistivity survey of 200m Schlumberge sounding.
3. Multiple array measurement method: direct rho-s calculation for 4 pole sounding, Wenner, Schlumberger, Dipole-Dipole &Pole-Pole arrays.
4. Can measure many relative parameters like SP, polarization rate (IP survey), apparent resistivity and so on.
5. Full automatic for mapping in archeology and vertical electrical sounding.
6. Storage capacity: >16000 data points
Main applications
1. Widely used in metal ore prospecting, non-metal ore's detailed and general survey to decrease the venture of mineral investment and improve exploration success rate and scientificalness.
2. Applied in underground water detect to meet the demand of drinking water, industrial usage and agricultural irrigation.
3. Also used in engineering geological prospecting, disaster geological detect, coal goaf, archaeological mining, city exploration, non-metal pipe survey as well.
