1. Simple introduction:
Making using of the relative parameters of apparent resistivity method and IP survey, with DC power supply to earth, the instrument will determine whether there is any abnormity after data receiving and processing. It has 10 kinds of electrode arrays: 4-pole Vertical Electrical Sounding (VES), 3-pole VES, 4-pole profiling, combined profiling, mid-gradient, 5-pole VES, buried electrodes, dipole-dipole, two-pole, surface-borehole electrical method. The detect depth is up to the geological condition, about 500~1000m.
2. Main application:
1. Widely used in detailed and general survey of metal ores and non-metal ores.
2. Applied in underground water seeking, also in city prospecting, railway & bridge engineering exploration, geothermal investigation and coal goaf detect as well.
3. Main features:
Small volume, light weight: It integrates the transmitter and receiver into one case, and can do apparent resistivity and induced polarization measurement method simultaneously.
Multi-parameters measurement: It can directly display first potential(Vp), SP(Vsp), current(I), apparent resistivity(Ro), apparent polarizability(Ms), half- time(Th), degree of decrement(D), degree of deviation(R) and general parameters of stimulating(Zp). It can also do relative high density resistivity measurement by matching 60 channels or 120 channels high density switch.
More flexible and convenient operation: Apply full digital automatic measurement, which can do auto-compensation to SP, drift and electrode polarization.
Large LED screen can directly show 9 electrode arrays; Using keyboard to input the array parameters; After measuring one point, it can display resistivity curve, apparent polarizability curve, half-time curve etc.
Data interpretation is more convenient: The device can store the data of 4800 points, and each point has 22 data. Connect with RS-232 serial port, the stored data will be transmitted to PC for various digital analysis through corresponding software.
Beautiful configuration and firm: Large screen display, film full sealing multilayer panel; Interior power supply has multiple over-voltage and over-current auto-protection function to apply in various field environment.
