ATAGO's Abbe Refractometers are highly reliable instruments that measure Refractive Index.

Compared with other types of refractometers, the Abbe refractometers are capable of measuring liquid and solid samples such as plate glasses, plastic sheets, and other solid films.

NAR-2T - High-Temperature Model 

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.

Optional accessories: Circulating constant temperature bath (up to 60°C).

NAR-4T - High Refractive Index Model

Research and Development on new materials for modern technologies is being actively conducted in every industry. Many of these materials (especially polymer film and related materials) are of high refractive index - often too high for the existing Abbe refractometers. These can now be measured with the nD 1.4700 to 1.8700 range of the NAR-4T.

*Dispersion values cannot be measured with this unit.
