The popular Hot Disk® TPS 2500 S is the core instrument of our portfolio. This multi-purpose, highly performing R&D thermal conductivity meter is designed for precision analysis of thermal transport properties of materials of all types: solids, liquids, powders, and pastes. It is frequently used in automated production line QC testing. The TPS 2500 S handles sub-millimeter-thick bulk samples, has a Thermal Conductivity range of 0.005 to 1800 W/m/K, and accommodates temperatures from cryogenic to 1000°C. It can also analyse the anisotropic thermal transport properties of uniaxial materials. The TPS 2500 S is a capital research instrument, meets ISO 22007-2 and ASTM E3088-25, and is CE marked.
