Product Description

Main Application:
 
This resistivity and IP instrument is Widely used in metal and non-metal resources exploration, civil geophysical prospecting, railway and bridge prospecting etc, it also can be used in hydrology and engineering geology prospecting such as underground water exploration, dam foundation setting out and dam hidden danger exploration etc. This resistivity and IP instrument can be also applied to geothermal prospecting.
 
Main features:
 
Integrating advanced transmitting and receiving technology in one instrument, this resistivity and IP instrument is portable and flexible.
Using CMOS large-scale integrated circuit, with special standby operation mode, small in size, low consumption, multi-function, the resistivity and IP instrument will auto shut down if there's not any operation in 10 minutes.
 
Impeccable anti-interference technology--using multilevel filtering signal enhancing, integrated electrical interference rejection (powerful anti-common/differential mode interference ability), provides high measuring precision.
Auto SP, drifting and pole polarization compensation.
Receiving part has instant input overvoltage protection, transmitting part has overvoltage, overcurrent and AB open circuit protection.
All the measured data on the survey line can be showed on the display as a curve, the measuring result is intuitive and clear.
Full-english panel and menu prompt, 16 buttons in total, convenient to operate.
With simplified calculating system the  routine calculation for field surveying parameter can be easily done. 
This resistivity and IP instrument can arbitrarily set the work cycle, nine different field survey working modes includes electrode distance, equipment input and calculation settings.
Electrode distance table : for all electrode arrangement you can pre-store 100 groups of different electrode distance constants into the resistivity and IP instrument storage, with one serial number you can call-out relevant electrode distance data to use or to reset, this function can help avoiding input error which caused by repeatedly inputting of one electrode distance constant. 
 
Ground resistance checking--you can check the ground resistance anytime you want, easy and feasible.
Extra large data storage--in DC resistivty and IP measuring mode, the instrument can store 2250 measure points (3500 measure points in self-potential mode).
This resistivity and IP instrument has power-off protection for parameter setting and measuring data, the data will not lose when you turn the instrument off or change battery.
With RS-232 interface this instrument can connect to other computers.
With customized diagnostic program, this resistivity and IP instrument can detect the fault location and damaged parts fast and accurately.
Imported full-sealed outer housing which has advantages such as damp-proof, dust-proof, long service life etc.
