Refractive Index

Atago Refractive Index Refractometers include the analog and digital (handheld, benchtop, Abbe and inline process) refractometers for measuring liquids, solids, and films.

The analog and digital handheld nD refractometers are easily transported for quick readings. The digital benchtop and multi-wavelength Abbe refractometers offer wider range refractive index measurement and ultra-high accuracy.
Automatic digital display refractive index are the easiest to use should always be considered over an analog viewer if possible.
