Thermal Conductivity Meter
There are a number of possible ways to measure thermal conductivity, each of them suitable for a limited range of materials, depending on the thermal properties and the medium temperature. Three classes of methods exist to measure the thermal conductivity of a sample: steady-state, time-domain, and frequency-domain methods.
About Instrument and its Applications:
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 1000ºC. 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 is CE marked.
