Simple Brix Digital Refractometer – ToronDR™ SB
A Digital Refractometer in the ToronDR™ SB is built for quick sugar-content checks in water samples, foods, fruits, and crops. This Brix Refractometer measures 0.0–55% Brix with a portable, battery-powered design for on-the-spot use. The Simple Brix Digital Refractometer – ToronDR™ SB is simple and fast to operate, lightweight, and easy to carry for field and production work.
Simple Brix Digital Refractometer – ToronDR™ SB uses optical principles to measure sugar concentration and supports two working modes: sugar content (Brix) and refractive index. It is positioned for food and beverage production, agriculture, and agricultural food processing where operators need quick checks without a benchtop instrument. The device is designed for small sample volumes, fast test time, and easy portable operation.
Simple Brix Digital Refractometer – ToronDR™ SB Application
- Food and beverage production checks: this instrument supports routine Brix screening for juices, syrups, and processed foods where soluble-solids control impacts taste and batch consistency. ISO 2173 provides recognized method context for refractometric determination of soluble solids in fruit and vegetable products.
- Agriculture and crop quality screening: field teams can use Brix readings to compare crop ripeness and sugar development during harvesting decisions and grading. The Simple Brix Digital Refractometer is used for fruits and crops and is widely used in agriculture and agricultural food processing.
- On-site QC and incoming inspection: the ToronDR™ SB is practical for incoming checks and quick batch comparisons because it needs only a few drops of sample and delivers results in seconds. Its small size and low-power battery operation support portable workflows.
Simple Brix Digital Refractometer – ToronDR™ SB Key Features

Theory and Method
A digital refractometer measures how light bends through a liquid sample, then converts that optical response into a numerical result. ToronDR™ SB applies this principle to display Brix for sugar-content work and can switch to refractive index mode when needed. Automatic temperature compensation helps reduce temperature-related reading drift during routine testing.
