Hot Disk Method to Measure Thermal Conductivity

The Hot Disk method enables the simultaneous testing of Thermal Conductivity, Thermal Diffusivity, and Specific Heat for a wide range of materials within a single measurement. This method eliminates the necessity for repetitive calibrations or reliance on standard samples. It offers flexibility allowing measurements on a wide range of samples (solids, liquids, powders, slurries) at temperatures ranging from liquid nitrogen to 1000ºC.  Contact agents and surface modifications are unnecessary, making this approach highly adaptable and efficient for comprehensive thermal property analysis.

Key Features of Hot Disk Thermal Properties Analyzer

  • Uniquely engineered to monitor ultra-short transient temperature readings, these instruments can handle thin samples and highly thermally conductive materials, achieving performance up to 1800 W/m/K.
  • The Hot Disk systems are shipped fully calibrated. You can rely on Hot Disk instruments without the hassle of recurring returns for external recalibration.
  • The analyzer can accommodate an extensive array of sensors ranging from 0.5 mm to 30 mm in radius.
