Sodium Chloride SX2 Handheld Refractometer (VeeGee Scientific) is exceptionally simple to operate and provides a quick, accurate measurement for the concentration of nearly any aqueous solution.

Operation consists of placing 1 or 2 drops of sample on the prism, closing the daylight plate over the sample, then looking through the focusable, cushioned-rubber eyepiece for the readings. Easy to calibrate, simply a few drops of distilled water or liquid standard (R.I. oil or prepared sucrose solution) on the prism, turn the built-in “Zero-Ring” until the shadowline is at the correct value of the liquid, and secure the ring.
