Built to travel, engineered to explore
TEM geoscanners and mobile apps enable survey teams to work faster and more accurately, delivering high-resolution data to significant depths.
Our TEM technology
The Transient Electromagnetic (TEM) geophysical survey method is a modern technique designed to measure vertical resistivity profiles with particular sensitivity to conductive materials.
- Particularly sensitive to conductive materials
- Non-invasive method using wire loops to transmit and receive signals
- Leaves no trace on the survey site after data collection
- Highly efficient, requiring a transmitter loop and one or two smaller receiver coils
- Can achieve depth measurements of up to 600 meters
- Entire process takes only a few minutes, from setup to resistivity modeling
Where to use TEM
TEM surveys are highly versatile and are particularly effective in the following areas. Our instruments deliver accurate, fast data to solve many geophysical challenges.
Groundwater Exploration: Identifies freshwater reserves, saline water, and contamination zones to optimize well placement and drilling depth.
Mineral Detection: Locates mineral deposits based on their unique resistivity signatures.
Geological Mapping: Reveals the subsurface structure for various geological studies.
Environmental Surveys: Assesses contaminants and salination in the soil.
The benefits of TEM
Transient Electromagnetic (TEM) mapping is a non-invasive method that ensures that survey areas remain undisturbed, as it uses wire loops to transmit and receive electromagnetic signals without leaving physical marks on the terrain.
TEMcompany geoscanners enable fast, accurate geophysical data collection alongside easy instrument setup, delivering significant time savings for consultants, contractors, and clients.
