Soil Thermal Instruments

Hukseflux Thermal Conductivity Sensors Hukseflux specialises in the measurement of thermal conductivity of plastics, composites, fluids, pastes, and granular materials like soils. Special capabilities include the measurement of composites in two directions (fiber and perpendicular to the fiber orientation), and the measurement of thin plastic and metal foil materials.
Decagon KD2 Pro The KD2 Pro is a fully portable field and lab thermal properties analyzer. It uses the transient line heat source method to measure thermal diffusivity, specific heat (heat capacity), thermal conductivity, and thermal resistivity. Sophisticated data analysis is based on 30+ years of research experience on heat and mass transfer in soils and other porous materials.

Request Quote    |    Brochure FTN01 Field thermal needle system for thermal resistivity/ conductivity measurement The FTN01 Field Thermal Needle System allows performing fast, on-site measurements of the thermal resistivity or conductivity of soils, in particular around the typical depth of burial of high voltage cables. FTN01 is designed with a focus on robustness and saving time, while still offering sufficient accuracy for typical field measurements. The sensor is a Non-Steady-State Probe (NSSP), TP09, which is mounted at the tip of the Lance LN01. The system is operated using a hand-held Control and Readout Unit CRU01.
Request Quote    |    Brochure MTN01 Multi-purpose thermal needle system for thermal resistivity/ conductivity measurement The MTN01 Multi-purpose Thermal Needle System allows performing fast measurements of the thermal resistivity or conductivity of soils. It is specifically designed to be reasonably robust, as well as accurate. It is therefore suitable for laboratory as well as field- measurements of soil thermal properties. The sensor is a Non-Steady-State Probe (NSSP), TP07, which is mounted on the Insertion Tool, IT02. The system is operated using a hand-held Control and Readout Unit CRU01.
Request Quote    |    Brochure 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 D 5334-00, D 5930-97 and IEEE 442-1981 standards. The standard TP02 probe has proven suitability in soils, thermal backfill materials, sediments, 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.
Request Quote    |    Brochure CRC Series Calibration reference cylinders for thermal needle probes TP02/TP08, TP07 and TP09 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.

Request Quote    |    Brochure NR01 4-Component Net Radiation Sensor NR01 is a 4-component net-radiation sensor that is used for scientific grade energy balance studies. The instrument has separate measurements of solar (Short Wave or SW) and Far Infra-Red (Long Wave or LW) radiation. Major improvements relative to comparable instruments include weight (reduced), solar offsets in the LW signal (reduced), ease of leveling (high, because leveling assembly is included).
