TP02 , Thermal Properties Sensor:

The TP02 Thermal Properties Sensor is a high-precision probe designed to measure the thermal conductivity (or thermal resistivity) of various materials quickly and accurately. It complies with ASTM D5334-14, D5930-97, and IEEE 442-1981 standards and is suitable for use in soils, thermal backfill materials, sediments, foodstuffs, powders, sludges, paints, glues, and other substances. The probe utilizes the Non-Steady-State Probe (NSSP) method, providing rapid and absolute results regardless of sample size. Developed in collaboration with the Applied Physics Group of Wageningen University, this sensor is ideal for both in-situ field experiments and laboratory applications.
