HFM / GHP
Thermal conductivity and diffusivity are the most important thermophysical material parameters for the description of the heat transport properties of a material or component.
Based on an absolute measurement method, the GHP 456 Titan® is the ideal instrument for the determination of Conduttività TermicaThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity of insulations.
The thermal conductivity as another significant thermophysical property is determined by means of heat flow meters (HFM) with the plate method for insulators.
NETZSCH instruments are based on the respective instrument and application standards for HFM (e.g. ASTM C518, ISO 8301, DIN EN 12667 EN 12, JIS A 1412, based on DIN EN 12664) and for GHP (ISO 8302, ASTM C177, DIN EN 12939, DIN EN 12667, DIN EN 13163).
Thermal conductivity and diffusivity are the most important thermophysical material parameters for the description of the heat transport properties of a material or component. Usually, thermal conductivity is determined by Heat Flow Meters (HFM) and Guarded Hot Plate (GHP).
