Optical Refractometers

Optical refractometers work in ambient light with no battery or other power source necessary. They can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two of a sample on the prism and read the results immediately. With reasonable care, their reliability, precision and optical performance will last forever.
Handheld refractometer by Sper Scientific, with automatic temperature compensation, having a black, textured grip.
