Determination of Thermal Diffusivity and Thermal Conductivity
For the precise measurement of thermophysical properties such as thermal diffusivity, the Laser Flash technique (LFA) has proven itself as a fast, versatile, and precise absolute method.
We offer four LFA models, which cover the entire spectrum of materials and temperatures:
- LFA 467 HyperFlash®
- LFA 457 MicroFlash®
- LFA 467 HyperFlash® HT
- LFA 427)
Our instruments are based on the respective instrument and application standards for LFA (e.g., ASTM E1461, DIN EN 821-2, DIN 30905, ISO 18755, ISO 22007-4, BS EN 1159-2, ASTM C714, etc.).
The thermal conductivity (λ) of insulation materials can be determined directly with plate instrumentation (HFM = Heat Flow Meter or GHP = Guarded Hot Plate): Included are the HFM 446 Lambda with its new, expanded measurement capabilities and the GHP 456 Titan® guarded hot plate, which is an absolute method and thus requires no calibration.
These instruments operate in accordance with relevant instrument and usage norms.
