Product overviewThe Guarded Heat Flow Meter (GHFM-22) conforming to ASTM E1530 measures steady-state axial thermal conductivity of solid samples at ambient temperature. The instrument imposes a controlled axial temperature gradient and determines thermal conductivity from measured temperature differences and heat flux. The GHFM-22 is a benchtop thermal conductivity meter suitable for metals, building materials, insulation, polymers and thin films, designed for fast, repeatable material characterization and laboratory tests.
