Using A Reflectometer During Fermentation. Is There A Formula?

Hello fellow Vintners.

 

I purchased a reflectometer with the hope of using it throughout the primary fermentation period. Of course, as many have stated that the reflectometer cannot be used to replace a hydrometer. However, I have also noticed that there seems to be a linear relationship between the reduced brix as measured by the reflectometer and the hydrometer through the fermentation process.

 

for example, immediately after crushing both devices showed a brix of 26. a few days later the reflectometer showed 13.5, while the hydrometer showed 5.5, then after a week, the reflectometer showed 9.6 and the hydrometer showed 0.

 

to anyone's knowledge is there a formula or method that can convert the readings of the reflectometer to that of a hydrometer?

 

thank you all !
