HotDisk is a high-performance instrument for testing the thermal conductivity of materials
2. It can simultaneously detect thermal conductivity, thermal diffusion, and heat capacity, with a wide range of applications
3. From insulation materials to high heat dissipation materials, it can be tested and is currently the most widely used and tested thermal conductivity meter in the world
4. Various testing modules can be added according to customer needs for software upgrades.
Currently, Hot Disk offers five testing modules: Standard testing module, Thin Film testing module, Slab testing module, Anisotropy testing module, and Specific Heat testing module.
6. It can test various types of materials with extremely low to extremely high thermal conductivity.
