Product Description

1D 2D Electric Sounding and Electrical Profiling Geophysical Resistivity Meters

 

 

The WGDM-3 Geophysical Resistivity Meters are a versatile tool for geophysical surveys that offers several useful features. Some of these features include:

1.Multiple electrode arrays: With 18 types of electrode arrays available, the device can be customized to suit different survey needs.

2.Extendable cross-section roll-along scan measurement: This feature allows for long cross-section surveys to be conducted without adding more electrodes. It is a cost-effective and efficient solution for solving geologic problems.

3.Schedule memory: The device can store up to 100 groups of electrode distances, which can be recalled using a schedule ID and set step. This feature avoids repetitive input and saves time.

4.Earth resistance inspection: The device allows for earthing conditions to be inspected at any time, ensuring accurate and reliable measurements.

5.Mass data storage: The WDJD-3A has ample storage capacity, with the ability to 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. This feature enables large amounts of data to be collected and analyzed for comprehensive geophysical surveys.
