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. -
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.

TRSYS01 is a high-accuracy system for on-site measurement of thermal resistance, R, thermal conductance, the Λ-value, and thermal transmittance, the U-value, of building envelopes. TRSYS01 is mostly used for measurements according to standard practices of ISO 9869 and ASTM C1155 / C1046. The system is equipped with high-accuracy electronics, two heat flux sensors of model HFP01 as well as two pairs of matched thermocouples. The two measurement locations provide redundancy, leading to a high level of confidence in the measurement result. The high accuracy of the heat flux sensors and temperature difference measurements ensures that TRSYS01 continues measuring when other systems no longer perform; in particular at very low temperature differences across the wall.- Temperature difference sensors: tested for 0.1 °C accuracy requirements
- Superior heat flux sensor, stable: waterproof (IP67), corrosion-proof
- Continues measuring when others give up: high sensitivity amplifier + high sensitivity sensors

VMA01 is a practical mounting adapter that, when combined with PMF01, helps mounting VU01 externally ventilated pyranometers on a vertical mast, horizontal crossarm, flat wall, or fence. It allows for horizontal as well as tilted (Plane of Array) orientation. The use of VMA01, compatible with a Hukseflux pyranometer ventilated by VU01 ventilation unit, is easy.- quick installation
- easy leveling using PMF01 spring-loaded bolt
- mounting a VU01 ventilated pyranometer with a PMF01, horizontal or tilted

VU01 is a high-quality ventilation unit for use with pyranometers and pyrgeometers. Its purpose is to improve the dependability of the measurement. Measurement accuracy improves because offsets are reduced. Reliability benefits from prevention of dew and frost formation and quick evaporation and sublimation of water and snow. ISO/TR 9901 “Solar Energy - Field Pyranometers - Recommended practice for use” recommends use of ventilators where high accuracy and reliability are required. VU01 is designed in agreement with the recommendations of ISO/TR 9901 and BSRN.- VU01 provides an airflow over the instrument body and dome and has two heaters on board to heat the air.
- VU01 is designed, using high-quality materials, in agreement with the recommendations of ISO/TR 9901 and BSRN.
- The footprint of VU01 is small, which prevents accumulation of snow
- Dew and frost formation is prevented.
