Held Refractometer Model GE-139
A pocket refractometer
designed on the principle of total reflection for measuring the
refractive index . The built in occular scale gives direct reading for
percentage of Sugar density. Packed in a beautiful velvet box.
A) Sugar scale 0-32% in division of 0.2 %
B) Sugar scale 0-50% in division of 0.2%
C) Sugar scale 58-92 % in division of 0.2%
D) Sugar scale 28-62% in division of 0.2% combined with nD 1.377 to
1.440 for NaCl reading.
