Laser thermal conductivity meter LFA 427

Having the widest temperature measurement range

For the description of thermal conductivity of materials or components, thermal conductivity and thermal diffusion coefficient are the most important thermal property parameters. Laser flash method is the most widely used method in the field of thermal conductivity testing, used to accurately measure the thermal diffusion coefficient of materials and calculate their thermal conductivity. The laser thermal conductivity meter LFA 427 launched by Nike represents the highest level of similar products worldwide.

LFA 427 has outstanding advantages such as high precision, high repeatability, fast measurement, diverse sample holder types, and freely adjustable testing atmosphere. Its total measurement temperature range is -120 ° C... 2800 ° C.

LFA 427 has recently launched a special configuration version with a pyrometer, which can measure over a wide temperature range from room temperature to 2800 ° C.

The sample of LFA 427 has a wide range of applications, including ceramics, glass, metals, melts, liquids, powders, fibers, and multilayer materials. From low thermal conductivity materials to diamond with the highest thermal conductivity, measurements can be taken at the same speed and accuracy. The instrument directly tests the thermal diffusion coefficient that varies with temperature, and when combined with the specific heat value (usually used) DSC 404 F1 Pegasus^® Testing can also be conducted using the comparative method on LFA 427, and density (the change of density with temperature can be measured using a thermal expansion instrument) can be compared DIL 402 Expedis By measuring and calculating, the thermal conductivity can be further calculated.

The laser energy, pulse width, atmosphere, and vacuum used for measurement can be freely selected, and the optimal measurement conditions can be set for different sample properties.

This instrument has a completely sealed system and is designed to save space. Its safety level has reached the highest level (Level 1), and no special safety measures are required during operation. The software features advanced functionality, allowing the instrument to operate in manual or fully automatic mode. And provide special brackets for testing powder, liquid, slag, fiber, and interlayer samples.

LFA 427 is the most powerful and flexible LFA system, suitable for characterizing conventional materials and new high-performance materials in various fields including automotive manufacturing, aerospace, and energy technology.
