DiFluid Refractometer for Coffee: Summary

This is a summary page of the multiple tests done on the first DiFluid digital refractometer and their second refractometer the R2. For someone interested in a cheaper refractometer, DiFluid seems to be an interesting option especially for espresso. However, the variability across devices made it difficult to make a more qualified assessment.
