• FTN02

    Field Thermal Needle System for Thermal Resistivity / Conductivity Measurement

    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.
    • Suitable for on-site (field) surveys
    • Easy data processing
    • Local calibration / conformity assessment
  • GT Series

    Guiding Tubes for Thermal Needles TP02, TP07 and TP08

    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.
  • IR20 & IR20WS

    Research Grade Pyrgeometers

    IR20 is a research grade pyrgeometer suitable for high-accuracy longwave irradiance measurement in meteorological applications. Thanks to Hukseflux’  technological innovation, IR20 is offered at a significantly lower price level than competing models of the same performance level. IR20 is capable of measuring during both day and night. In absence of solar radiation, model IR20WS offers even better accuracy because of its wider spectral range.
    • Breakthrough pricing for a pyrgeometer
    • Correction of temperature dependence by use of the measurement function
    • High sensitivity
    • Fast response time (3 s)
    • On-board heater
  • TP02

    Non-Steady-State Probe for Thermal Conductivity Measurement

    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
