• The pollution degree is 2 (according to IEC60664).
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.
Special scales 23 most commonly measured concentration scales are pre-programmed.
History function Up to 500 most recent measurements can be displayed and printed.
