The Wincom ABBE Refractometer is a classic and highly durable optical instrument designed to measure the refractive index (nD) of transparent or translucent liquids and solids, as well as the sugar concentration (Brix percentage) in solutions. It is widely used in sugar refining, pharmaceutical, food, beverage, petroleum, and chemical industries, as well as in school and university laboratories.

Technical Specifications

• Refractive Index Range (nD): 1.3000 to 1.7000

• Refractive Index Accuracy: +/- 0.0002 nD

• Refractive Index Minimum Division: 0.0005 nD

• Brix Measuring Range: 0 to 95 percent

• Brix Minimum Division: 0.2 percent

• Temperature Range for Measurement: 0 to 50 degrees Celsius

• Weight and Dimensions: 6.5 kg, 140 x 200 x 270 mm

• Observation Mode: Monocular visual telescope system with internal scale

Key Features

• Traditional Optical System: Features a clear visual alignment system with a crosshair and internal scale graduation for accurate manual readings.

• Dual Scale Measurement: Measures both Refractive Index (nD) and Sugar Percentage (Brix) simultaneously through the eyepiece view.

• Built-in Thermometer Connector: Comes with a dedicated thermometer socket to monitor the exact temperature of the prism area during testing.

• Constant Temperature Control: Equipped with water nozzle inlets to connect an external circulating water bath, ensuring precise temperature regulation for sensitive samples.

• Robust Construction: Built with a heavy metal base and corrosion-resistant optical prism assembly for long-term laboratory durability.

Primary Applications

• Agriculture and Sugar Industry: Estimating sugar levels (Brix) in sugarcane, honey, syrups, and molasses during production.

• Quality Control in Food and Beverage: Checking concentrations in juices, sauces, milk, and dairy products.

• Chemical and Petrochemical Labs: Determining the purity of organic solvents, oils, lubricants, and synthetic materials.
