Small and light weight geophysical resistivity meter for 500m deep water detection
Introduction:
The WDDS-3C geophysical resistivity meter is a specialized
instrument designed for geophysical surveys that do not have access
to an external power source. It features an internal high
transmitting power that allows it to operate without an external DC
power source.
The instrument is equipped with a built-in 12V lithium battery that
provides up to 20 hours of continuous work. It can also support an
external 12V battery if needed, providing additional power for
extended surveys.
In terms of data storage, the WDDS-3C geophysical resistivity meter
is capable of storing measuring data for more than 150,000 times.
The stored data includes voltage, current, resistivity, relative
error, SP, array constant, measuring point, and other relevant
information. This makes it easy to store and analyze large amounts
of data from multiple surveys.
Overall, the WDDS-3C is a specialized geophysical resistivity meter
designed for surveys in remote locations or areas without access to
an external power source. Its internal high transmitting power and
long battery life make it suitable for extended surveys, while its
large data storage capacity makes it easy to collect and analyze
large amounts of data.
