Introduction to the Atago MASTER-TA Refractometer

The Atago MASTER-TA refractometer (Cat. No.: 2590) is a handheld optical measuring device from Atago (Japan), specially designed to measure total acidity (T.A.) and Brix. The instrument is primarily used for testing grape must concentrations and monitoring wine production and processing. With a compact and rugged design, it delivers high convenience and reliability for users both in the laboratory and in the field.

Outstanding features

• Total acidity (T.A.) scale from 0,0 to 25,0 % and Brix scale from 0,0 to 40,0 %, optimized for grape and wine samples.
• Integrated automatic temperature compensation (ATC), ensuring stable and accurate measurement results even with sample temperature variations.
• Meets IP65 water-resistance standards, allowing easy cleaning under running water and safe operation in humid environments.
• Compact mechanical handheld design, simple operation, suitable for both professional and amateur winemakers.

Applications

• Check grape ripeness, sugar, and acid content at the harvest vineyard or raw material receiving area.
• Control fruit juice and grape must concentration before and during wine fermentation stages.
• Analyze and assess finished wine quality at wineries and testing laboratories.
• Used in research and training in the field of fermented beverage technology.
