Using a refractometer is possibly the quickest and easiest way to check gravity throughout the brewing process. A refractometer is not as commonly used by homebrewers as a hydrometer but I find using one is much easier for quick readings so this article i

Specific Gravity Measures density of a liquid in relation to the density of water, which has a specific gravity of 1. Calibration and Use of Analog Refractometers. Calibrate the refractometer with a standard solution before use. Since the reading will be

A refractometer is a tool used for measuring concentrations of aqueous solutions. It has many applications across food, agricultural, chemical, and manufacturing industries. A refractometer can be used to measure things like the total plasma protein in a
