Refractometer » Refractive Index

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.

Refractometers turn light into answers. This guide explains refractive index, Brix and salinity scales, compares handheld, digital, Abbe and inline types, and walks you through calibration, care and selection. Practical checklists and workflows help QA teams, growers and engineers get reliable, fast measurements.
