Refractometer » Quality Control

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.

Digital refractometers turn how light bends through a liquid into clear coolant glycol and Brix readings. This guide shows you how to choose the right instrument, run reliable field tests, set calibration schedules, and avoid common errors, with real examples from automotive shops and orchards.
