Electrical Resistivity Survey For Groundwater Investigation Induced Polarization Instrument

The WDJD-3A multi-function digital dc resistivity & ip instrument has changed the traditional electrical exploration equipment's large size, heavy weight, and insufficient professional use, making the instrument more miniaturized, lighter, and supporting intelligent analysis software, with simple operation and use Distinguished feature of convenience.

Main Features and Functions

• Simple calculator fulfills calculation of geometric factor and other calculations on the spot.
• For general resistivity and IP survey function, 8 types of electrode arrays are available. Electrode distance (namely “Schedule”) can be inputted or called. Geometric factor K can also be generated automatically or calculated manually.
• For multi-electrode 2D resistivity imaging function, 18 types of electrode arrays are available. Extendable cross-section roll-along scan measurement allows the measuring cross-section to be prolonged unlimitedly without adding more electrodes. It is suitable for long cross-section survey and for solving geologic problems under any condition with low cost and high efficiency.
• Schedule: the schedule can memorize 100 groups of electrode distances, avoiding repetitive input. Or you just input a schedule ID and set step to call the corresponding electrode distances.
• Earth resistance inspection: earthing condition can be inspected at any time.
• Mass data storage: WDJD-3A can memorize 3500 readings of data for resistivity and SP survey, 2500 readings of data for induced polarization (chargeability) survey and 43680 readings of data for multi-electrode 2D Resistivity Imaging.
• All parameter and data are under power-failure protection; and thus data will not be lost even thought the system shuts down accidentally.
• RS-232C port enables it to transfer data to computer.
• Diagnostic program finds fault or failure and damaged parts quickly and accurately.
• Sealed constitution: featuring waterproof and dustproof design, long life time and so on.
