Calibration Oil Refractive Index and °Brix Calculator
Refractive Index values are calculated from a data fit of empirical results,
which is valid over the range 10 and 75 °C (from batches BSLP24 & BSDC17
onwards – previous batches between 20 and 75°C only). The values
used to determine this relationship were produced from a statistical evaluation
of averaged refractive index data measured on a high accuracy refractometer
at 589.3nm. °Brix values are equivalent scale values in accordance with
the relationship between Refractive Index and °Brix published by ICUMSA.
Refractive Index and °Brix values will only be displayed if the temperature
is within the stated range.
Note: Results derived from these calculations at any temperature
other than 20.0°C are outside the scope of Bellingham + Stanley Ltd.’s
UKAS Calibration Accreditation. °Brix values greater then 85.00 are extrapolated
from the relationship given in ICUMSA SPS-3 (2000) Equation 2.
