The Hot Disk® TPS 500 S rapidly and accurately measures the Thermal Conductivity, Thermal Diffusivity, Thermal Effusivity and Specific Heat Capacity of a wide range of materials and is therefore an excellent step-in thermal conductivity meter, and uniquely suitable for QC testing. The TPS 500 S adds powerful new features to the 500-series, in accommodating e.g. more measurement modules and sensor models. The TPS 500 S can handle bulk sample sizes down to a thickness of a few millimeters, has a Thermal Conductivity range of 0.03 to 200 W/m/K, and its temperature span is from -100°C to 300°C. It is partly based on ISO 22007-2 and ASTM E3088-25, and is CE marked.
