Product Description
Vee Gee Scientific CTX-2 Handheld Refractometer, with Antifreeze/Coolant Scales, -50 to 32 degree F Freezing Point: Industrial & Scientific. Prism: optical glass. VEE GEE X-Series Handheld Refractometers are exceptionally simple to operate and provide quick, accurate measurements for the concentration of nearly any aqueous solution. Easy to use: 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. Accurate: Featuring the largest, easiest-to-read scale available with clear, sharp figures, screen shading, and incredible contrast. These features significantly enhance overall accuracy even when several different operators use the instrument. Tool-free calibration: The VEE GEE exclusive 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 shadow line is at the correct value of the liquid, and secure the set screw that's it. Durable: 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 placed on a table or bench top, they won't be prone to roll off the surface.
