Hanna Lab - Learn About the Hanna Instruments Baum¨¦ Wine Refractometer HI96812
- Sample size as small as 2 metric drops (100 μl)
- Sealed stainless steel well with high-grade optical prism made of flint glass
- Fast 1.5 second response time for temperature compensated readings
Details
The HI96812 portable refractometer converts the % Brix of a wine, juice or must sample to °Baume. This conversion is based on tables found in the Official Methods of Analysis of AOAC International, 18th Edition. One °Baume is approximately equal to 1.8% Brix and 1% alcohol when the wine is fully fermented. The HI96812 is an easy to use tool for winemakers for measuring sugar in grapes or must, in the field or in the lab.
- Designed for wine sugar analysis
- Temperature Compensation algorithms based on sucrose solution
- 0 to 28°Baume range with an accuracy of ± 0.1°Baume
Refractive Index
The HI96812 takes measurements based on a sample’s refractive index. Refractive index is a measurement of how light behaves as it passes through the sample. Depending on the sample’s composition, light will refract and reflect differently. By measuring this activity with a linear image sensor, the sample’s refractive index can be assessed and used to determine its physical properties such as concentration and density. In addition to the linear image sensor, the HI96812 uses an LED light, prism and lens to make measurement possible.
Variations in temperature will affect the accuracy of refractometry readings, so the use of temperature compensation is highly recommended for reliable results. The HI96812 contains a built-in temperature sensor and is programmed with temperature compensation algorithms in accordance with the ICUMSA Methods Book Standard for a percent by weight sucrose.
