Hanna Instruments HI 96801 Digital Refractometer, 0-85% Brix Range, For Sugar Analysis

The Hanna Instruments HI 96801 is a portable, waterproof meter that measures the refractive index of samples in order to display sugar content in a substance, 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 meter 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 meter has a range of 0 to 85%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). The meter uses the methodology from the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis). Its dimensions are 19.2(W) x 10.2(D) x 6.7 (H) cm, and it weighs 420 g.

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.
