Product Details

Product Overview

RussiaVNIIOFIThe eutectic point was developed by the All Russian Institute of Optical Physics Measurement, which belongs to the Russian Federation's technical control and metrology department. Currently, RussiaVNIIOFIEutectic points have been applied in multiple national metrology institutes and have received widespread praise from users.

Note:The eutectic point container is used in conjunction with a high-temperature blackbody radiation source, and the size of the container using the same eutectic point varies on different high-temperature blackbody radiation sources.
