Main applications for soil thermal conductivity measurements are off-shore oil and on-shore high voltage cable route survey analysis. See reference users for application use and applicable sensor products.

Thermal Route Survey Analysis
Hukseflux is a global market leader in the field of non-steady-state needle type thermal conductivity and resistivity sensors, including fully automated turnkey thermal conductivity measurement systems. Non-steady-state thermal needles are most commonly employed in soil thermal conductivity and resistivity measurement studies.

Hukseflux offers two ranges of thermal needles and turnkey system solutions:

1. The TP02 and TP08 thermal needle models, and the TPSYS02 measurement system, are intended for highest accuracy level laboratory based thermal conductivity and resistivity analysis.
2. The FTN01, MTN01 and TNS01 thermal conductivity and resistivity measurement systems are designed specifically for routine field use, employing heavier gauge thermal needles than the TPSYS laboratory system model; the field systems are more robust in construction and are portable in design for ease of use in the field.

The FTN01 and MTN01 systems also serve as replacements for the BAUR thermal conductivity probes, including the Onwood 227 system, manufactured by BICC of England.

Hukseflux also manufactures custom thermal conductivity sensors and measurement systems upon request to suit specialized customer application requirements. Such sensor/system applications include heavy duty models for routine field use, to miniature sensor models for thermal conductivity analysis within small samples (e.g. radioactive materials, uranium sludge, foods, etc.) Extra short and hardened sensor models have also been developed by Hukseflux for use in offshore soil thermal resistivity measurements in core samples.

Reference users of Hukseflux thermal needles and system products include world leading geotechnical companies like Fugro (branches USA, Saudi Arabia, The Netherlands), Norwegian Geotechnical Institute, Battelle (USA), Arab Center for Engineering Studies, EGS (UK and Hong Kong branches).
