This beer refractometer has it all! It features a Plato scale, Dissolved Solids scale, Specific Gravity (D 20/20) scale, Bewer's Points scale, and a propylene glycol freeze point scale. Use the Dissolved Solids scale for precisely measuring the sugar content of wort used in beer making. The Dissolved Solids, Points, and Specific Gravity scales are based on the mathematical relationship between real wort sugars and refractive index so they will provide a more accurate indication of true sugar content and can be used interchangeably with Brix, Plato, and Balling units in calculators and equations.The Plato scale is based on the relationship between sucrose and refractive index. The propylene glycol scale is ideal for measuring propylene glycol heat transfer fluid (antifreeze) in wort coolers and chiller systems. Whether you are a beer chemist working for a multinational brewery, or a passionate brewer crafting one-of-a-kind beer in your own home, the goal of the MISCO Digital Beer Refractometer is to help you by providing the most accurate possible beer measurements from start to finish. The MISCO Digital Beer Refractometer is not just a repurposed Brix refractometer. MISCO Pro-Brewing Scales are scientifically derived from a beer model with a very complex sugar profile, which is influenced strongly by maltose, and specific to wort. As there is very little sucrose in wort, measurements and temperature compensation are naturally much more accurate than sucrose-based Brix refractometers. Furthermore, because the refractometer is made specifically for beer, the user no longer needs to use a refractometer correction factor when plugging dissolved solids or specific gravity readings into beer calculators. *Digital Beer Refractometer shown here with optional Rubber Armor Jacket - Available Separately.
