This beer refractometer features both a Plato and a Brewer's Points (20 C) scale equipping it to make standard measurements of wort used in beer making. The Plato scale is based on the mathematical relationship between sucrose and refractive index, as are all Plato refractometers. However, the Brewers Points scale was scientifically derived from a beer model with a very complex sugar profile, which is influenced strongly by maltose, the primary wort sugar. As there is very little sucrose in wort, Brewers Points measurements are naturally more accurate than sucrose-based refractometers. Both scales are automatically temperature compensated for true wort sugars. 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. Fast, convenient, and easy to use, the MISCO Digital Beer Refractometer requires only a fraction of the sample size required by traditional hydrometers. Simply place a drop or two of wort in the stainless steel well and press a button. The beer refractometer delivers a nearly instantaneous digital readout on a large backlit LCD display. The digital readout removes the subjectivity associated with interpreting where a boundary line crosses tiny little scale divisions. *Digital Beer Refractometer shown here with optional Rubber Armor Jacket - Available Separately.
