Product Description

The Hanna Instruments HI 96821 brix refractometer is a portable meter for measuring salinity levels in food preparations.

The HI 96821 measures salt content in aqueous food solutions, with results available 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 96821 converts the refractive index of the sample to one of four popular units for measuring salinity: g/100 g, g/100 mL, Specific Gravity, and degrees Baumé.

The 9V battery operated device utilizes a yellow LED as a light source, and automatically powers off after three minutes of non-use. The HI 96821 has a range of 0 to 28 g/100 mL, 0 to 34 g/100 mL, 1.000 to 1.216 specific gravity, or 0 to 26 degrees Baumé. Temperature compensation is automatic between 10 and 40 degrees C (50 to 104 degrees F).

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 can be used to ensure proper salinity levels in aqueous solutions.

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 assure the quality of its products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.
