Geophysical Water Exploration Instrument and Underground Water Detector
Digital DC resistivity instrument
It is a new generation intelligence multi-electrode resistivity instrument. It can automatically measure and memorize voltage, current, apparent resistivity, and SP parameter. It is widely used in the hydrological and engineering survey, such as ground water seeking; dam base evaluation and flood control dam incipient fault and so on. It also can be applied in engineering geological prospecting, such as metal-nonmetal mineral resources exploration, urban exploration, railway and bridge, even in the geothermal exploration..
Features:
Transmitter and Receiver is all in one, it is portable and flexible.
Super storage capability ---- more than 150000 times. (including voltage, current, resistivity, relative error, SP, array constant, measuring point and so on)..
Quality monitoring----- Automatic display electrical resistivity and relative error between current measuring result and last measuring result. Memorizing the measuring result and relative error at the same time..
Array constant table----Memorizing 30 different array constant, avoiding repetitive input, input number can invoke polar distance or reset.
Electrode array -----Calculate eight kinds of ordinary constant of field electrode array automatically, or input special electrode array constant directly.
Super-low power consumption -----CMOS large scale integrated circuit, stand-by current low to 30mA, automatic cut-off when the stand-by time overtime.
Automation-----Automatic SP compensation by single-chip microcomputer (SCM), gain adjustment, filtration and signal enhancement.
Safeguards-----Over-voltage protection, over-current protection, high-voltage opposition protection, AB open-circuit protection, power-fail protection.
On-line operation----RS-232 serial interface on-line work with other microcomputer.
RS-232C port can communicate with other computers.
Self-diagnostic function ----- Self-diagnostic function to fault location and main damage device.
All sealed constitution---Water-proof, dust-proof, long life and so on
