ABV Calculator
This calculator may be used in place of the existing lookup tables supplied
with the Eclipse “Alcohol” refractometer. Simply
input the refractometer and the SG readings and the program will calculate % alcohol by
volume to two decimal places!
NOTES:
1, The purpose of providing 2 decimal place results is to allow
users to benefit from better resolution of the table data and is not intended
to offer a higher accuracy reading. The calculation of ABV by way of hand held
refractometer and hydrometer is still limited by instrument performance, especially
with respect to the temperature and achievable accuracy of the hand held refractometer.
As such, the typical accuracy of % ABV vol/vol remains as published at ±0.5%.
2, Refractometer
readings (Zeiss values) must fall between 15 and 130 and specific gravity
between must be between 0.9 and 1.1. The results (values) will only be displayed
if the input parameters are within these limits and the calculated ABV is
in the range 0 to 25.6.
