Refractometer » Salinity & Aquaculture

Master refractometry without the fluff. Learn what a refractometer measures, the difference between digital and optical, how to use ATC correctly, and a repeatable workflow for reading, converting Brix to SG, and calibrating with water or certified standards—across lab and field use.

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.
