Atago NAR-3T High-Precision Abbe Refractometer

The Atago NAR-3T is the flagship model of the NAR series, meticulously engineered to provide the highest level of measurement accuracy and operational efficiency. By implementing fundamental improvements to the optical system, incorporating a larger scale, and utilizing a high-intensity LED lamp, it achieves a professional accuracy of ±0.0001 nD for refractive index and ±0.05% for Brix. The innovative dual control knobs allow for both rapid adjustment and fine-tuning, ensuring meticulous results with unprecedented ease of use.

Designed for high-tech research and industrial quality control, the NAR-3T covers an expanded range of 1.30000 to 1.71000 nD and can measure the refractive index of liquids, glass, plastics, and films. It also provides essential data on Abbe numbers (optical dispersion) through calculated average dispersion values. With its robust 6.8 kg construction and support for external temperature-controlled circulators, the Atago NAR-3T is the ultimate laboratory instrument for scientists who require extreme precision in optical material analysis and high-concentration Brix determination.
