Abbe refractometer NAR-4T

laboratorybenchtop

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. Range - Refractive index (nD) : 1.4700 to 1.8700 Minimum Scale - 0.001 Accuracy - ±0.0002 Measurement Temp. - 5 to 50ﾟC (Temperature range available of the circulating water) Light source - LED (Approximating to wavelength of D-Line) Dimensions & Weight - 13×18×23cm, 2.5kg (Refractometer) 10×11×7cm, 0.5kg (Thermometer)
