• Page 3: General Description

  The HI 96831 refractometer is an optical device that is simple and quick to use. Samples are measured after a simple user calibration with distilled or deionized water. Within seconds, the refractive index and temperature are measured and converted into one of two measurement units;...

• Page 4: Principle Of Operation

  In the HI 96831 refractometer, 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 5: Measurement Units

  MEASUREMENT UNITS Freezing point is displayed as a temperature from 0.0 to -50.0 °C corresponding to 0-58 % by volume. The display blinks the freezing point when the concentration of Ethylene glycol is greater than 78 % concentration by volume. When the display shows “LO”, the freezing point is at a minimum (below -50 °C).
