Designed for use with compounds that require measurement at high temperatures (up to 120°C). Capable of measuring samples from 5 to 120°C, such as substances with a melting point higher than room temperature, or compounds containing substances with a transition temperature below 120°C. Aside from liquid samples, glass, films, plastics and other solid samples can also be measured.
This model is suitable to measure the higher refractive index of NAR-2T which enables to measure by high temperature up to 120℃.
*Optional accessories: Circulating constant temperature bath (up to 60°C). (Pg. 5) For a circulating constant temperature bath above 61°C, please purchase separately (not available through ATAGO).
