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.
