VeeGee Scientific X Series Handheld Analog Refractive Index Refractometers

VeeGee Scientific X Series Handheld Analog Refractive Index Refractometers are exceptionally simple to operate and provide quick, accurate measurements for the concentration of nearly any aqueous solution.

  • Largest & sharpest display scale available
  • High-quality optical glass material ensures consistently accurate readings
  • Patented “Zero-Ring” requires no calibration tools
  • Durable, industrial grade design
  • One year warranty

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. This model features the largest, easiest-to-ready scale available for clear, sharp figures, screen shading, and incredible contrast. All units feature rubber grips on the body, which block the transmission of hand heat to reduce temperature errors.

Feature “Zero-Ring” calibration - simply place a few drops of distilled water or liquid standard (R.I. oil or prepared salt solution) on the prism, turn the built-in “Zero-Ring” until the shadowline is at the correct value of the liquid, and secure the knob.

The prism is mounted in an all-metal housing which allows the sample and prism to reach temperature equilibrium quickly. Also feature non-roll stands to ensure that once the units are paced on a table or bench top, they won’t be prone to roll off the surface.
