Refractometer » Handheld Digital Refractometers

This guide explains how refractometers work, compares handheld, Abbe and inline types, and shows how Brix, salinity and refractive index readings support food, beverage, automotive and pharma workflows. Learn the basics of Brix–SG conversion, ATC and calibration so your measurements stay consistent.

Learn how refractometers convert light into practical scales like Brix and RI, then apply quick workflows for handheld and lab devices. We cover ATC, calibration, and maintenance, plus when to pick digital vs analog so your readings stay consistent across field and production.
