Options | • Container TP08: Because of the relative importance of the thermal equilibrium between base and sample, an optional container can be ordered with TP08. • Alternative designs: Hukseflux is specialised in NSSP design. Alternative models, for instance smaller, more robust or temperature resistant have been manufactured on request. • Permanent installation in soils: The dedicated model TP01 is specifically designed for long term monitoring. A separate brochure is available. |
Frequently asked questions
How do I choose the right instrument for measuring thermal properties?
Hukseflux offers a wide range of products for material characterization and measurement of thermal conductivity.
We can offer assistance in choosing the right instrument. But first, you should ask yourself the following questions:
- what material should be analyzed?
- what are the conditions, for instance concerning temperature and pressure?
- what specimens are available?
- are there standards for my application?
- what level of accuracy do I need?
Hukseflux is a leading manufacturer of thermal conductivity measuring systems and sensors. We have prepared a guide which may assist you in choosing the proper instrument for measuring thermal properties of your material, whether it is soil, plastics, paints, composites, pastes and fluids.
Hukseflux is able to offer highest quality products at an acceptable price level. If we cannot offer you an acceptable solution ourselves, we will tell you who can. Please contact us for further assistance.
Where are the sensors (needle, probe, meter) for measuring thermal conductivity?
Hukseflux sells a range of complete measuring systems including sensors and Measurement and Control Units (MCU). We offer systems and needle type thermal properties sensors for use in the field and for use in laboratory environments.
These thermal properties sensors, TP02 and TP08, are also available as separate probes for use with the user’s own electronics, for instance Campbell Scientific CR1000.

Can I get training or a rental system for the thermal conductivity measuring instrument of my choice?
Expert training for system operators
Although in general the systems can be operated by following manuals and standards, we can provide you with expert training. Training vastly improves the level of service to the third party, the efficiency of working with the equipment and reduces the uncertainty of the end result.
Equipment rental
Unfortunately we have discontinued our rental services for all systems.
