Display method 7.5-inch color LCD + touch screen
Display with top and
bottom limit bar A visual indicator to approximate the measured value within a set range.
It can be turned off.
User scale When 3 to 5 points of a user scale corresponding to the Refractive Index are
inputted,
The internal software will automatically create the conversion formula.
Unit of measure (%, g/100g, g/100ml, mol/l, %max, %vol, no unit) can be
displayed.
