A.KRÜSS Optronic Handheld refractometer scales, ranges and model accuracies

Not arbitrarily. They represent different sample relationships and model ranges.
Why
HR information lists Brix, NaCl and honey water-content scales separately. Multiple scales on one model do not mean every sample can be interpreted on any scale.[1]
Automatic temperature compensation (ATC) applies under specified scale and sample conditions. It is not a universal conversion and does not imply identical features across models.
What to confirm
Identify the sample, then the exact model’s scales, ranges and temperature functions. Do not treat Brix in complex samples as unvalidated true sugar content or convert salinity to another component without an applicable relationship.
