Electrical Resistivity and IP Survey Equipment
Geotech develops and manufactures electrical resistivity and induced polarization equipment for engineering, environmental, groundwater and mineral exploration surveys.
The product range includes multichannel electrical resistivity tomography systems, portable resistivity meters, electrical survey transmitters, multifunctional receivers and equipment for 2D and 3D subsurface investigations
Geotech electrical survey instruments can be used for:
- electrical resistivity tomography (ERT);
- vertical electrical sounding (VES);
- electrical profiling;
- induced polarization surveys;
- self-potential measurements;
- engineering and hydrogeological investigations;
- groundwater and mineral exploration;
- environmental and infrastructure surveys.
Available configurations include complete systems integrating a transmitter, receiver, electrode switching unit, field cables and data processing software, as well as individual transmitters and receivers for specialized survey configurations.
The appropriate equipment depends on the required survey method, investigation depth, number of electrodes and measuring channels, transmitter power, terrain conditions and data processing requirements.
Contact the Geotech engineering team to compare available systems and receive a recommended equipment configuration for your project.
How to Choose Electrical Survey Equipment
Do I need a complete ERT system or separate instruments?
A complete ERT system is suitable when you need an integrated transmitter, receiver, electrode switch, cables and processing software. Separate transmitters and receivers are more appropriate for specialized or expandable configurations.
Which equipment is suitable for 2D and 3D resistivity tomography?
Multielectrode systems such as OMEGA-48 and SKILL PRO are intended for automated resistivity imaging. The appropriate system depends on the number of electrodes, channels, profile length and required survey depth.
Which instruments support induced polarization surveys?
Several Geotech systems and components support induced polarization measurements, including integrated resistivity systems, specialized transmitters and IP receivers.
Can Geotech configure a complete survey system?
The configuration may include the measuring instrument, transmitter, receiver, switching unit, electrodes, field cables, power supply, computer and processing software.
