Product Description
Resistivity Meter Geophysics WDDS-2C Geo Resistivity Equipment
WDDS-2C/3C digital resistivity meter (hereafter also referred to as WDDS-2C/3C mainframe or WDDS-2C/3C meter) is a new generation of DC resistivity equipment which is based on a series of advanced electrical equipment of resistivity survey, and adopts 32-bit micro-controller technology and 24-bit A / D technology development.
This geo Resistivity meter applies for metal and nonmetal mineral resources detection, city geophysical exploration, railway and bridge inspection and so on. The geophysical Resistivity meter can use for hydrology and engineering geology as seeking for ground water, inspecting dam base and flood protection levee for incipient faults, geothermal prospecting.
Difference of WDDS-2C and WDDS-3C Resistivity meter
1. WDDS-2C is equipped with 7.4V lithium battery with automatic protection which can auto-power-off when battery voltage is lower than 6.6V.
2. WDDS-3C has a 7.4V lithium battery for working power and a built-in 48V high-voltage power supply as transmitting power supply. The 48V power can transmitting 50V, 100V, 150V, 200V DC high voltage
Difference of WDDS-2 and WDDS-2C Resistivity Meter
WDDS-2 stop production, now update to WDDS-2C.
WDDS-2C Control with Tablet PC
Windows 10 64 bit operating system, memory no less than 2GB, storage capacity no less than 32GB, Bluetooth, USB.
