Place a small amount of liquid (usually 2–5 drops) on the prism and secure the cover plate. This will evenly distribute the liquid on .Temperature Correction Table For Refractometers Calibrated At 20°C (l=589nm) Source: ICUMSA, 1974 Model BX-90 is factory-calibrated to conduct readings at 20°C. For the best accuracy, if ambient temperature falls above . This refractometer is an optical instrument -- it can become damaged if dropped or handled in a rough manner.The most amazing feature is that the digital refractometer can utilize multiple temperature correction tables for different fluids over a wide temperature range. A digital refractometer can also be custom programed to measure your specific fluids and can have custom temperature compensation tables as well. Most refractometers measure from 0-32° Brix, with an accuracy of +/- 0.2° Brix. Some also include automatic temperature compensation for temperatures between 50-86° F, which eliminates the need to consult temperature correction charts. You must consult a chart to convert the reading in °Brix to Specific Gravity.
Some refractometer models include an automatic temperature correction feature Calibrate your device. The application of water is an effective calibration method, as long as it is the same temperature as the liquid you plan to measure.
Because the Brix scale is an assessment of specific gravity the reading is sensitive to temperature. The observed Brix reading can be corrected for temperature using the following scale. The Brix scale is set for a temperature of 20 C, below this temperature the solution is less dense than the reading indicates so the table gives the value to subtract to obtain the .A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from the observed refraction angle using Snell's law. . Temperature has a very important influence on the refractive index measurement. Therefore, the temperature of the prism and the temperature .
The refractive index can be read directly from the built-in scale by looking into the refractometer. Optical refractometers with Brix scales for the determination of sugar concentration are available for purchase. However, for more precise . Never use paper (including Kim-wipes) to clean the refractometer prisms! Never "scrub" the prism! Temperature correction.
