L: 5.25 x W: 3.25 x H: 1.7
Great new refractometer from Asico in China. This model has an internal light source using two AA batteries. The glass hemisphere is made of Cubic Zirconia, much harder than the lead glass used in Duplex II and other refractometers, and
it is resistant to corrosion that refractive index liquid can cause over time. A superior refractometer in all respects. Comes with a polarizing filter for determining birefringence, with hard and soft cases.
