HI96811

Description

The HI96811 is a rugged, portable digital refractometer designed for sugar measurement of juice and must. The HI96811 reports sugar content as % Brix and has a high accuracy of ±0.2%. The operation of the meter is simplified with only two buttons: one button is to calibrate with distilled or deionized water and the other to take a measurement. All readings are automatically compensated for temperature variations according to the ICUMSA Methods Book standard and displayed within a 1.5 second response time. The sealed flint glass prism and stainless steel well are easy to clean. Just wipe with a soft cloth in preparation for the next sample.

•  Fast 1.5 second response time for temperature compensated readings
•  Sample size as small as 2 metric drops (100 μl)
•  Sealed stainless steel well with high-grade optical prism made of flint glass

The HI96811 Digital Refractometer converts the refractive index of a juice or must sample to % Brix. This conversion is based on the tables found in the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis) that documents the changes in refractive index with temperature for a percent by weight sucrose solution. Since the majority of sugar in grape juice and must is fructose and glucose instead of sucrose, the reading is sometimes referred to as “Apparent Brix”. Typical grapes at harvest will be between 19-24% Brix or degrees Brix (^°Bx). The HI96811 is an easy-to-use tool for winemakers for measuring sugar in grapes or must, in the field or in the lab.

•  0 to 50% Brix range with an accuracy of +/- 0.2% Brix
•  Designed for winemaking sugar analysis
•  Temperature Compensation algorithms based on sucrose solution
