The article deals with thermal diffusivity measurements by using of thermovision techniques. Methods for determination of thermal parameters of insulating bodies are time consuming and so that, their utility in industry is inconsiderable. For example such measurements can’t be used for online inspection of product quality. In the article, new method for determination of thermal diffusivity was presented. Basic concept and model of measuring device were discussed. The method is characterized by short measuring time, high accuracy and low dependence on external conditions. Exemplary measuring results were presented and all advantages of proposed method were proved.
