Original, Irreplaceable, A true classic
This model is suitable to measure the lower refractive index of NAR-2T which enables to the measurement of the high temperature up to 120℃.
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.
ATAGO's Abbe Refractometers are widely used in a variety of fields; from basic research to product management.
Uses and Applications
For measuring the refractive index (nD) of liquid samples between 5 to 50˚C: | DR-A1, DR-A1-Plus, and NAR-1T LIQUID. We recommend the NAR-3T for high-accuracy measurements. |
For measuring the refractive index (nD) of liquid samples up to 120˚C: | NAR-2T |
For measuring the refractive index (nD) of solid samples (glass, plastics, films, etc.): | NAR-1T SOLID, DR-A1, and DR-A1-Plus. The NAR-3T is also capable of measuring clear, translucent glass or plastics. |
For measuring liquid or solid samples with a high refractive index (1.47 to 1.87): | NAR-4T |
For measuring and determining the refractive index or Abbe number of liquid or solid samples at different wavelengths: | DR-M Series: DR-M2, DR-M2/1550, DR-M4, and DR-M4/1550 (For high refractive index measurements.) |
For determining average dispersion values or abbe numbers: | NAR-1T SOLID, NAR-2T, and NAR-3T |
For measuring Brix (%): | DR-A1, DR-A1-Plus, and NAR-1T LIQUID. We recommend the NAR-3T for high-accuracy measurements. |
For connecting to a printer: | DR-A1, DR-A1-Plus, and DR-M Series |
For measuring birefringent (double refraction) samples (plastics, films) that have different refractive indices depending on their orientation, or for measuring the ordinary ray (n subscript null) or extraordinary ray (n subscript exponential) of liquid crystals (LCs): | DR-A1, DR-A1-Plus, NAR-1T SOLID, NAR-2T, NAR-4T, and DR-M Series |
