Atago PR-RI Digital Refractive Index Refractometer

The Atago PR-RI is a high-precision digital handheld refractometer specifically engineered for measuring the Refractive Index (nD) of liquid samples in pharmaceutical and chemical applications. Designed to replace subjective manual readings with meticulous digital data, it ensures reliability and speed in professional laboratories. By placing just a few drops of the sample on the prism and pressing the start button, the refractive index and temperature are displayed simultaneously within seconds.

Featuring an exceptional resolution of 0.0001, the PR-RI is a powerful tool for substance identification and purity verification. Its rugged construction, powered by a standard 9V battery and protected by a professional hard carrying case, makes it suitable for both benchtop research and on-site quality control. The Atago PR-RI combines laboratory-grade optical diagnostics with user-friendly operation, providing a modern digital solution for meticulous liquid analysis.
