Abbe Refractometer NAR-4T cat. no 1240

R& D 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. But these are now covered with the nD1.4700 to 1.8700 range of the NAR-4T.
