Geophysical Resistivity Instruments Digital DC Surface Electrical
Testing Device for Mineral Exploration
PRODUCT DESCRIPTION
The WDDS-2C/3C digital resistivity meter, also known as the
WDDS-2C/3C mainframe or WDDS-2C/3C meter, is a new generation of DC
resistivity equipment that uses 24-bit A/D technology development
and 32-bit microcontroller technology. It is based on a series of
advanced electrical equipment of BTSK for resistivitysurvey. It can
be used in the following fields: hydrology and engineering geology,
such as looking for groundwater, checking the foundation of dams
and flood protection levees for impending faults, detecting metal
and nonmetal mineral resources, city geophysical exploration,
railway and bridge inspection, and geothermal prospecting.
MAIN FEATURE
- Bluetooth technology, wireless remote control: The tablet PC can control the WDA-1/WDA-1B mainframe up to 10
meters away using Bluetooth technology. It makes all tasks, such as
setting parameters, starting measurements, displaying results, and
saving data, easier.
- Tablet PC operate, powerful function:All activities, including parameter setting, data display, storage,
and curve drawing, may be completed on a tablet PC, making data
processing easier and more apparent.
- Grounding resistance check: This function allows the operator to determine the ground
condition of each electrode.
- Fault diagnoses:The diagnostic application instantly detects faults and locates
damaged parts.
- Sealed configuration:Featuring a waterproof, dust-proof design and a long lifespan.
- Light and flexible: The modern transmitter and receiver are designed as one unit with
a small dimension and light weight. The built-in (only WDDS-3C)
200V high-voltage power supply allows you to easily handle the
majority of survey work without the need for an additional bulky
battery box.
- Large power supply, wide range, high precision: 6000W (1200V * 5A) power supply capacity, 100Vp-p wide voltage
input range, high accuracy measurement of small signals, allowing
equipment to perform effectively in high resistance locations and
providing access to deeper and better measurement results.
APPLICATION
- Investigating Ground Water
- Bed Rock Examination
- Geological Structure Delineation
- Identification of Sand and Gravel Deposits
- Examining Minerals
