VEE GEE Scientific X-Series Handheld Refractometers

From $111.95
List Price From $124.00

VEE GEE Scientific X-Series Handheld Refractometers are exceptionally simple to operate and provide quick, accurate measurements 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. This model features the largest, easiest-to-ready scale available for clear, sharp figures, screen shading, and incredible contrast. These features significantly enhance overall accuracy… even when several different operators use the instrument. All units feature rubber grips on the body, which block the transmission of hand heat to reduce temperature errors.

The VEE GEE® patented “Zero-Ring” eliminates the hassle of using a separate tool for calibration. Simply place 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 set screw.

The X-series models feature rugged construction to provide years of reliable use. 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.

Choose from Brix, Salinity Refractive Index (nD), coolant (freezing point of Ethylene & Propylene Glycol), Battery Charge Level, Urea, and NaCl. Models BTX-1, BTX020, STX-3, STx-1, & STX-2 features ATC, which free the user from having to re-calibrate in the work environments with large temperatures swings. The effective compensation range is 10-30°C.
