ATR-ST Automatic Critical-angle Refractometer
The new ATR-ST an critical angle refractometer for the measuring of liquid media from low to high
viscosity, and independent of opacity and colour. The ATR instrument are available in a variety of
configurations for laboratory and production quality control.

ATR-ST S plus Automatic Critical-angle Refractometer
The “S plus model” distinguishes itself by a higher resolution and precision in comparison to basic
model and the model ATR-ST plus.
-Measuring range 1,28000 - 1,54000 nD/0 - 100 Bx
-Resolution 0,00001 RI / 0,01 Bx
-Precision ± 0,00003 nD / ± 0,02 Bx
-Measurement of liquids from low to high viscosity
-Irrespective of opacity and colour
-0.3 ml sample volume is sufficient
