Description
Product Introduction:
This instrument is designed and manufactured in accordance with the JGT 469 test method for determining the thermal diffusivity of foam glass. It employs a computer‑based interface to facilitate data acquisition, processing, display, and printout.
This instrument determines the thermal diffusivity of materials by means of a cooling‑based temperature‑reduction method and is widely used in manufacturing enterprises, quality‑inspection agencies, higher education institutions, and research institutes.
Working principle:
After raising the sample temperature to a specified level and allowing it to reach thermal equilibrium, the thermal diffusivity of the sample is determined from its cooling rate at that stable temperature.
Technical Specifications:
