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. Model NAR-4T Cat.No. 1240 Measurement range Refractive index ( nD) 1.4700 to 1.8700 Minimum scale Refractive index ( nD) 0.001 Measurement accuracy Refractive index ( nD) ± 0.0002 Digital Thermometer Indication range 0.0 to 50.0° C ( Accuracy ± 0.2° C Minimum indication 0.1° C ) Measurement Temperature Range 5 to 50° C Light Source LED Power Supply AC100 to 240V , 50/ 60Hz Power Consumption 5VA Dimensions & Weight 13× 18× 23cm, 2.5kg ( Refractometer) 10× 11× 7cm, 0.5kg ( Thermometer) Optional • Test piece A with m-naphthalene : RE-1195 • Test piece D for measurement of film : RE-1498 • Test piece E for measurement of film : RE-1499 • Monobromona-phthalene as contact liquid : RE-1196 • Methylene iodide containing sulfur solution : RE-1199 • Contact liquid LJ : RE- 99080 • Eyepiece for polarizing : RE-1146 * Calibration Certificate : Contact an ATAGO representative for details.
