Refraktometer » Automatic Temperature Compensation

Struggling with inconsistent Brix readings, coolant checks or lab values that never quite agree? This guide shows how refractometers really work, how to calibrate them properly, and when to choose handheld, Abbe or inline models so your concentration data is fast, reliable and audit-ready.

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.

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.
