The affordable Hot Disk® TPS 1500 is the ideal thermal conductivity meter for testing building materials, insulation materials or any other type of large bulk samples. The TPS 1500 Thermal Conductivity range comprises 0.01 to 400 W/m/K, and the instrument handles temperatures from -100°C to 750°C. Sample sizes down to a thickness of a few millimeters can be accommodated. It can also analyse the anisotropic thermal transport properties of uniaxial materials. The TPS 1500 meets ISO 22007-2 and ASTM E3088-25, and is CE marked.
