Page 3: General Description
All are equally valid ways to measure the sugar content of grape or must samples in the field or winery. The HI 96811, HI 96812, HI 96813 and HI 96814 are optical instruments that are based on the measurement of the refractive index of a solution. The measurement of refractive index is simple and quick and provides the vintner a standard accepted method for sugar content analysis. -

Page 5: Principle Of Operation
PRINCIPLE OF OPERATION %Brix, °Baumé, °Oechsle, °KMW and % potential alcohol determinations are made by measuring the refractive index of a solution. Refractive Index is an optical characteristic of a substance and the number of dissolved particles in it. Refractive Index is defined as the ratio of the speed of light in empty space to the speed of light in the substance. -
Page 6: Measurement Units
MEASUREMENT UNITS MEASUREMENT UNITS HI 96811, HI 96812, HI 96813 and HI 96814 measure sugar content in several units to meet the differing requirements found in the wine industry. HI 96811, HI 96813 and HI 96814 convert the refractive index of the sample to sucrose concentration in units of percent by weight, %Brix (also referred to as °Brix). -

Note: The last measurement value will be displayed until the next sample is measured or the instrument is turned off. Temperature will be continuously updated. Note: The ”ATC” tag blinks and automatic temperature compensation is disabled if the temperature exceeds the 10-40 °C / 50-104 °F range. 4. -
Page 12: To Change Temperature Unit
For HI 96814 only: 1. Press the RANGE key to select measurement units %Brix, °Oechsle (°Oe) or °KMW (°Babo). The instrument toggles between the three scales each time the key is pressed and the primary display indicates “bri” for %Brix, “OE” for °Oechsle or “bAbo” for °KMW. When the instrument displays the screen with 4 dashes the instrument is ready for measurement. -
