Thermal Diffusivity by Holometrix (Single Point)


Test ID  
T-311

   
Description  
The Holometrix microflash uses a laser to fire a short pulse at the surface of a thin disk specimen at a specified temperature between ambient and 300C. The heat transferred through the specimen results in a temperature rise on the opposite surface that is measured by an infrared detector. Analysis of this temperature change allows determination of thermal diffusivity.    
Options  
When combined with density and specific heat measurements, thermal diffusivity is used to calculate thermal conductivity for materials where the thermal conductivity can not be measured directly. Call to verify sample thickness.  
Standards  
ASTM E1461  
Data
