FTN02 Field thermal needle system performs accurate on-site (field) measurements of the thermal resistivity and thermal conductivity of soils. Measurements with FTN02 comply with ASTM D5334 and IEEE 442 standards. The system is specifically designed for surveys that require measurements from the surface down to a depth of 1.5 m. Due to the long and thin lance to which the sensor is mounted, the insertion of the thermal needle into the soil requires just a small-diameter access hole, typically made using a ground drill. Using a lance rather than digging trenches saves time. FTN02 is operated and powered from the hand-held control and readout unit CRU02. -
The MTN02 performs fast measurements of the thermal conductivity and resistivity of soils. Measurement with MTN02 complies with ASTM D5334 and IEEE 442 standards. The system is primarily designed for laboratory (indoor) measurements but can also be used for on-site (field) measurements. MTN02 is operated and powered from the handheld control and readout unit CRU02.- Suitable for laboratory and field measurements
- Suitable for hard soils and concretes
- Easy data processing
- Local calibration / conformity assessment

The GT series guiding tubes are accessories for Non-Steady-State Needle probes. They are intended to facititate measurements in hard soils, concrete, cement and bentonite. Also in case of measurements on large quantities of samples one can use several guiding tubes and one single needle. -
CRC's contain traceable thermal conductivity reference materials for calibration of Non-Steady-State Probes. There are several different CRC types. The geometry of the different types is adapted to fit needles with a certain diameter. Hukseflux is a leading supplier of Non-Steady-State Probes, and is the inventor of the CRC calibration method.- Amorphous plastic reference material does not have any directionally dependent thermal properties

TNS02 efficiently and accurately performs on-site (field) as well as laboratory measurements of the thermal conductivity and thermal resistivity of soils. The system is a combination of our FTN02 and MTN02 systems. Measurement with TNS02 complies with ASTM D5334 and IEEE 442 standards. It is designed for optimal flexibility. TNS02 includes two different needles; one on a short insertion tool for use in the laboratory, the other mounted on a long lance for use on-site. The control and readout unit, CRU02, is shared between the two (on-site and laboratory) needle models.- Efficient and accurate measurement of thermal conductivity and resistivity of soils
- Measurements both in the field and in laboratory environments

TP02 is a probe that offers the possibility to perform a practical and fast measurement of the thermal conductivity (or thermal resistivity) of the medium in which it is inserted at the highest accuracy level. It works in compliance with the ASTM D5334-14, D5930-97 and IEEE 442-1981 standards. The standard TP02 probe has proven suitability in soils, thermal backfill materials, sediments, foodstuff, powders, sludges, paints, glues and various other materials. The Non-Steady-State Probe (NSSP) measurement method (also known as transient line source, thermal needle, hot needle, heat pulse- and hot wire technique) has the fundamental advantages that it is fast and absolute while the sample size is not critical. Hukseflux is specialised in NSSP design. Special models have been developed for in-situ field experiments. For permanent installation in soils, a dedicated model, TP01, is available. TP02 has been designed and tested in collaboration with the Applied Physics Group of Wageningen University.- Optimal accuracy
- Temperature sensor in the base
- High temperature and moisture resistance

TP08 is a probe that offers the possibility to perform a practical and fast measurement of the thermal conductivity (or thermal resistivity) of the medium in which it is inserted at a high accuracy level. It works in compliance with the ASTM D5334-14, D5930-97 and IEEE 442-1981 standards. The TP08 is a small version of type TP02, made for situations where the length of the TP02 poses a problem. The standard TP08 probe has proven its suitability for soils, thermal backfill materials, sediments, foodstuff, powders, sludges, paints, glues and various other materials.- The standard TP08 probe has proven its suitability for soils, thermal backfill materials, sediments, foodstuff, powders, sludges, paints, glues and various other materials.
