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.
