Thermal conductivity and diffusivity are the most important thermophysical material parameters for the description of the heat transport properties of a material or component. For the precise measurement of thermophysical properties like the thermal diffusivity, the Laser Flash technique (LFA) has proven itself as a fast, versatile and precise absolute method. NETZSCH offers four LFA models, covering the entire spectrum of materials and temperatures.
Based on an absolute measurement method, the GHP 456 Titan is the ideal instrument for the determination of 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 LFA (e.g., ASTM E1461, DIN EN 821, BS EN 1159-2, ASTM C714, etc.), 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)
