Hanna Instruments HI 96811 Digital Brix Refractometer for Professional Wine Analysis

The HI 96811 Digital Refractometer is a portable meter measuring the refractive index of samples in order to display sugar content, displaying results within seconds.

To take a reading, the sample well must be calibrated with distilled or deionized water, followed by a few drops of the sample liquid. A dual-level LCD screen displays the measurement and temperature within several seconds. The HI 96811 converts the refractive index of the sample to sucrose concentration in units of percent by weight (%Brix, also referred to as degrees Brix).

The single 9V battery operated device has Automatic Temperature Compensation (ATC), and automatically powers off after three minutes of non-use. The HI 96811 has a range of 0 to 50 %Brix/0 to 80 degrees C (32 to 176 degrees F) with accuracy + or - 0.2 %Brix / + or - 0.3 degrees C (+ or -0.5 degrees F) and a resolution of 0.1 %Brix/0.1 degrees C (0.1 degrees F). It’s dimensions are 19.2(W) x 10.2(D) x 6.7(H) cm, with a mass of 420 g.

Hanna manufactures additional refractometers which measure sugar content in units such as degrees Baumé, degrees Oechsle, degrees KMW (utilized in the Austrian, German, and Swiss winemaking industries) and measure percent alcohol.

Refractometers measure refractive index, which is the optical characteristic of a substance and the number of dissolved particles in it. Refractive index is the ratio of the speed of light in empty space to the speed of light in the substance. Refractometers are often used in the beverage making process to determine sugar content.

Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents, and buffer solutions. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries. Hanna Instruments holds many firsts in the field of analytical instrumentation, including a pH electrode with a built-in temperature sensor, an electronic pocket-sized pH tester, and a replaceable electrode pH pocket tester. To ensure the quality of its products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.
