[ Problem Point ]
With conventional methods, it is difficult to maintain a uniform temperature and achieve localized heating, leading to challenges in measurement accuracy and reproducibility.
[ ⇒Kaizen Point ]
By using a halogen point heater, precise localized heating becomes possible, improving measurement accuracy and reproducibility. In particular, the ability to achieve both temperature maintenance and variation with a single heat source is a significant advantage in measuring thermal diffusivity using optical heating.
