- Page 7 In the HI96814, light from an LED passes through a prism in contact with the sample. An image sensor determines the critical angle at which the light is no longer refracted through the sample.
- Page 8 HI96814 converts the refractive index of the sample to sucrose concentration in units of percent by weight, %Brix (also referred to as °Brix). The conversion used is based on the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis). Since the majority of sugar in grape juice is fructose and glucose and not sucrose, the reading is sometimes referred to as “Apparent Brix”.

- Page 11 Calibration should be performed daily, before measurements are made, when the battery has been replaced, between a long series of measure‑ ments, or if environmental changes have occurred since the last calibration. 1. Press the ON/OFF key, then release. Two instrument test screens will be displayed briefly;...
- Page 12 Verify the instrument has been calibrated before taking measurements. 1. Wipe off prism surface located at the bottom of the sample well. Make sure the prism and sample well are completely dry. 2. Using a plastic pipette, drip sample onto the prism surface. Fill the well completely.
- Page 13 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.
- Page 14 To change the temperature measurement unit from Celsius to Fahrenheit (or vice versa), follow this procedure. 1. Press and hold the ON/OFF key continuously for approximately 15 seconds. The LCD will display the “all segment” screen followed by a screen with the model number on the primary display and the version number on the secondary display.
- Page 15 To make a Brix Solution, follow the procedure below: • Place container (such as a glass vial or dropper bottle that has a cover) on an analytical balance. • Tare the balance. • To make an X % BRIX solution weigh out X grams of high purity Sucrose (CAS #: 57‑50‑1) directly into the container.
- Page 16 To replace the instrument’s battery, follow these steps: • Make sure the instrument is off. • Turn instrument upside down and remove the battery cover by turning it counterclockwise. • Extract the battery from its location. • Replace with a new 9V battery making sure to observe polarity. •...
