A contrast Refractometer 0-32 A-Contrast Refractometer Erma Hand Refractometer (0-32%) Portable Sugar Content Tester SG Specific Gravity Tool Handheld Hydrometer for Measuring Sugars with Automatic Temperature Compensation 0-32% Refractometer Perfect for Sugar, Food, Beverage, Soybean Milk, Honey, Beer, Fruit, Fluid Sweetness, Saccharimeter, Wort, Alcohol, Wine, CNC Fruit Homebrew Manual Laboratory Measurement Kit This Refractometer is for measuring the sugar content of beer and includes an automatic temperature compensation of 10 – 30 degree Celsius. This Refractometer can replace your hydrometer for easier and more accurate measurements. Simply use the dropper to take a sample of wort and put it on the prism. Then hold the Refractometer up to the light and look through the eyepiece. Due to the dual scale there is no needing convert to specific gravity as the scale measures both Brix and SG. It is widely applied in measuring soybean milk concentration, sugar manufacturing, food and beverage.
This is an optical instrument
Measurement of % sugar in fruit and vegetables provides information on quality and may be used as an indicator of harvest time, market value or use as a fresh or preserved product.
Temperature affects the reading (increases 0.5% SSC for every 5°C or 10°F). The reading is only correct if done between 20-30°C (68-86°F). Otherwise use a correction table.
