Laser Flash Method Thermal Constant Measurement System TC-1200RH/TC-9000 series

Thermal conductivity measurements covering a wide range of materials not only thermoelectric materials but also metals, ceramics, carbon etc.
The systems measure 3 thermal constants (Thermal diffusivity, Specific heat capacity, Thermal conductivity) for uniform solid materials such as thermoelectric materials, ceramics, carbon, Metal, etc


  • Research and development of thermoelectric materials
  • Research and development of ceramics, metals and organic materials
  • Evaluation of thermal diffusivity and thermal conductivity of materials related to FPD
  • Research of thermal diffusivity of materials such as semiconductor devices and molded(Seal) materials


  • Specific heat measurement with contact and non-contact methods
  • Realize an uniform laser pattern (Patented)
  • Stabilized lower output laser power supply system(Patented)
  • Much better temperature controllability, stability with infrared gold image furnace (TC-1200RH model)
  • Available to measure thermal diffusivity at plane direction of thin film with a substrate measurement attachment
