In both cases, use a refractometer calculator to convert from the "brix" reading to specific gravity. The original and final readings are both needed in the same calulator. i.e. don't try to compute an FG specific gravity without having the original reading too. #2 VikeMan, Feb 11, 2016

WebOct 6, 2024 · As an example: Samples taken at 15oC – 40oC are corrected to a reference temperature reading of 20oC. Temperature correction or control is necessary because refractive index varies inversely with temperature, as temperature of sample rises refractive index falls and so as sample temperature drops refractive index will rise. WebA correction value of +1% when the prism cover is folded up. The corrected measurement result is therefore -1% + 1% = 0. A rule of thumb for temperature correction of refractometers with refractive index scales: Subtract 0.0001 to 0.0004 nD per °C with a device temperature of less than 20°, if the temperature is higher, add that number.
