Atago NAR-2T Abbe Refractometer

The Atago NAR-2T is a high-performance Abbe refractometer specifically engineered for the analysis of samples that require high-temperature environments. Distinguishing itself from standard models with an impressive operating range up to 120°C, it is the premier choice for measuring molten plastics, hot oils, and chemical compounds that must remain stable at elevated temperatures. It provides meticulous refractive index (nD) and Brix measurements for both liquid and solid samples.

Equipped to calculate Abbe numbers (optical dispersion), the NAR-2T maintains a professional accuracy of ±0.0002 nD even under intense heat. The instrument supports an external circulator bath to ensure precise temperature control during the weighing process. Featuring a built-in LED light source and a clear digital thermometer, the NAR-2T is an essential tool for polymer science, automotive lubricant manufacturing, and petrochemical R&D. It combines Atago's legendary optical precision with the rugged durability needed for demanding industrial laboratory applications.
