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
Accuracy: ±0.0002
Minimum Scale: 0.001
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)
