Beer Refractometer – Plato & Specific Gravity (D 20/20 °C)

MISCO Digital Beer Refractometer with Plato and Specific Gravity (D20/20) Scales

This beer refractometer features both a Plato and a Specific Gravity (D 20/20) 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 Specific Gravity 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, Specific Gravity measurements are naturally more accurate than sucrose-based refractometers (see our FREE technical bulletins under the Reference Material Tab). 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.

Precision is assured thanks to MISCO’s proven OPTICAL-ENGINE®, which is at the heart of every Digital Beer Refractometer. Optical-Engine technology features high-precision sapphire optics, the next hardest substance to diamond, which improves the speed and accuracy of temperature measurements. Competing digital refractometers only use glass prisms. A 1,024 element high-definition detector array provides more than eight times the resolution of competing 128 element low-definition detector arrays. The MISCO array has more than 3,256 pixels per inch (ppi) resolution compared with 400 ppi resolution in competing digital refractometers. The net result is an instrument that is more rugged and more precise.

Nonlinear temperature compensation is specific to beer, not sucrose, and automatically ensures that fluids read between 10 and 40 °C (50 to 104 °F) are measured accurately. Calibration is automatic and does not require the use of special calibration solutions or tools. The beer refractometer automatically calibrates itself to water and is ready to use in seconds. No more screws to turn and nothing to adjust. The output can even be localized to display in English, German, Spanish, French, and Russian.
