- Function: handheld refractometer for testing sugar content in liquids, measuring 0–90% Brix with automatic temperature compensation for fast, reliable readings. - Key benefits: quick, repeatable results; reduces guesswork in sugar measurement; supports consistent quality across batches. - Compatibility: suitable for homebrew beer, wine making, agriculture, horticulture, and educational use. - Build and materials: compact handheld unit with durable ABS housing and a glass measurement prism; easy to clean and maintain. - How it works: calibrate with distilled water; apply a few drops of sample to the prism; close the cover and read the scale with ATC adjusting for temperature. - Use scenarios: - Homebrewing: monitor wort sugar to gauge fermentation potential. - Winemaking or juice production: assess sweetness to guide harvest timing and bottling. - Agriculture or classroom labs: test fruit sap or plant extracts to study sugar distribution and ripeness.
