Hanna Instruments HI 96803 Digital Glucose Refractometer

The HI 96803 is a portable waterproof sugar refractometer. The meter measures the refractive index of an aqueous solution and provides results in percentage by weight concentration.

The refractometer uses methodology recommended by the ICUMSA Methods Book (internationally recognized organization for sugar analysis), and provides results in approximately 1.5 seconds. Calibration is performed with either distilled or deionized water, without the need of additional solutions. The light source is a yellow LED, and the sample cell is an SS ring and flint glass prism.

Sugar content range is 0 to 85% (by weight), with resolution + or - 0.1, and accuracy + or – 0.2%. Temperature range is 0 to 80 degrees C (32 to 176 degrees F) + or - 0.3 degrees C (0.5 degrees F). Minimum sample volume is 100 ul in order to completely cover prism. The device operates on one 9V battery, and features an auto-off function after three minutes of none-use. Dimensions are 192 x 102 x 67 mm (7.6 x 4 x 2.6") with weight 420g.

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.
