Atago NAR-4T Abbe Refractometer

The Atago NAR-4T is a specialized Abbe refractometer meticulously engineered for research and development on advanced materials with exceptionally high refractive indices. While standard refractometers often fall short in high-tech polymer and film analysis, the NAR-4T covers an expansive range from 1.4700 to 1.8700 nD. This makes it an indispensable instrument for the chemical, optical, and material science industries, specifically optimized for characterizing next-generation polymers and related high-index materials.

In addition to liquid samples, the NAR-4T is highly efficient in measuring solid samples and thin films, while also providing crucial data on Abbe numbers (optical dispersion). The device is compatible with specialized high-index contact liquids and test pieces, ensuring a perfect optical interface for meticulous measurements. Equipped with a high-intensity LED light source and a precise digital thermometer, it maintains a professional accuracy of ±0.0002 within a 5 to 50°C temperature range. The Atago NAR-4T combines advanced optical engineering with the rugged reliability required for professional industrial laboratory diagnostics.
