HD-DRM-II Thermal Conductivity Tester
(Heat Pulse Method)
The transient heat pulse method thermal conductivity tester is used to measure the thermal conductivity, thermal storage coefficient, thermal conductivity and specific heat of homogeneous plate-like, colloidal, powdery and granular materials under dry or different moisture conditions. It is suitable for testing inorganic materials such as thermal insulation materials, concrete materials, plastics, rubber, graphite, etc.
The characteristics of this instrument are: simple device, high accuracy, fast test speed (one test takes about ten minutes), and the thermal conductivity, thermal storage coefficient, thermal conductivity and specific heat of the material can be measured simultaneously in one test, and the thermophysical properties under different moisture conditions can be measured.
