Atago 1240 NAR-4T Abbe Refractometer.Refractive Index(nD) 1.4700 - 1.8700 ±0.0002 (minimum scale 0.001).
Digital Thermometer: 0.0 to 50.0°C ±0.2°C (minimum indication 0.1°C).
High Range Refractive Index Measurement. The NAR-4T analog Abbe refractometer is used for measurement of high range refractive index materials like polymer film and related materials.
Includes: Digital thermometer, lamp cord, illuminator lamp (8V 0.15A) 5pcs, calibration screwdriver, calibration test piece, contact liquid (monobromonaphthalene) 4ml, milky white reflector, tube bands 10 pcs and owner's manual.
View DatasheetR&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 measurement with existing Abbe refractometers. But these are now covered with the nD 1.4700 to 1.8700 range of the Type NAR-4T.
The digital thermometer provides an indication range of 0.0 to 50.0°C (Accuracy ±0.2°C, minimum indication 0.1°C)
