MODULAR architecture makes the Flashline perhaps  the most flexible system of its kind. It allows  the addition of other furnaces at a later date to grow  with changing needs. Including the multiple sample testing option pioneered by Anter. This feature not only produces a several times increase in productivity, but also makes the optional specific heat capacity measurement more reliable.


SIMPLE to operate and safe to use, the system is  suitable for research and development programs, as well as quality control. It is easy to maintain and very economical to operate in terms of consumables. The laser module is mobile and can be easily located near each furnace in a cluster arrangement. The output of the laser is channeled through a proprietary fiber optic wand to any of the selected furnaces. Pulse delivery through the fiber produces outstanding flux uniformity that greatly improves the data.

 

T HE method involves uniform irradiation of a small, disc-shaped sample over its front face with a very short pulse of energy. The time-temperature history of the rear face is recorded through high-speed data acquisition from a solid-state optical sensor with very fast thermal response, and thermal diffusivity is determined from the time dependant thermogram of the rear face. Thermal conductivity can be computed from measured values of thermal diffusivity and specific heat capacity, with the additional knowledge of density. Thus, a system can automatically determine thermal conductivity using the measured (or separately entered) heat capacity and thermal diffusivity, with separately entered density data. A unique feature of the system is the full-time pulse mapping and recording capability that allows precise pulse shape and
pulse width correction calculations. Standard configuration employs a 200-300μs pulse width.
