We love precision.

Laboratory and Field Investigation

GeoTec has more than 40 years of experience in theory and application of geophysical and thermal measurement technology. Our main objective in measuring is, that our results are based on a firm scientic foundation. We are more than measurement device operators - GeoTec is also busy in measurement device development and recent geophysical research. Thus, we always see the complete measurement environment and keep an eye on all potential error sources.
