Atago PR-RI Digital Refractive Index Refractometer (Palette Series)

Atago PR-RI is a digital Palette series refractometer that measures the refractive index of pharmaceutical active ingredients, solvents, and chemical formulations within seconds using a single-drop sample. Designed for pharmaceutical and chemical laboratories seeking fast, repeatable results for purity control and identity verification.

The instrument operates across a measurement range of 1.3306-1.4436 nD with 0.0001 nD resolution and ±0.0002 nD accuracy; it simultaneously provides temperature measurement from 5-45°C. Powered by a 9V battery with compact dimensions of 17×9×4 cm, it offers a portable configuration. The absence of temperature compensation and IP65 protection indicates design for controlled laboratory environments.

Compared to manual or gemologist-type refractometers, it enables measurement with significantly smaller sample volumes, in shorter timeframes, and with superior accuracy; this delivers time savings in high-throughput analysis workflows.
