Dual scale for versatile measurement: the main scale ranges from 0 to 40% with a precise 0.1% division, and it includes a proportion scale for quick crosschecks. Sturdy and compact construction: made from aluminum, this refractometer has a durable metal body that supports longlasting performance. Its compact size and rubberized grip make it easy to carry and use in a variety of environments. Clear and easytoread display: the scales are clearly visible for quick readings, and the soft, flexible eyepiece provides comfortable viewing for extended use. Instant and reliable measurements: simple manual calibration combined with a builtin Automatic Temperature Compensation (ATC) system delivers reliable measurements of aqueous solutions. ATC operates over a range of 10 C to 30 C (50 F to 86 F), helping maintain accuracy under varying temperature conditions. Key attributes Function: measures sugar content in aqueous solutions with a dualscale display Scale range and precision: 0 to 40% with 0.1% divisions Material: aluminum body for durability Design: compact and portable with a rubberized grip Performance: manual calibration plus ATC for temperatureadjusted readings from 10 C to 30 C Use scenarios Beverage and juice quality control: determine sugar content in fruit juices, syrups, and other beverages during production or quality checks Homebrewing and winemaking: monitor sugar levels during fermentation to guide process decisions Field testing and education: practical measurement of aqueous solutions in classroom demonstrations or onsite sampling
