Manufacturer: Vee Gee Scientific Brand: Vee Gee Scientific Model: SX-2

SX-2 Handheld Refractometer, 0-28% Sodium Chloride VEE GEE X-Series Handheld Refractometers are exceptionally simple to operate and provide quick, accurate measurements for the concentration of nearly any aqueous solution. Includes Carry Case (1 ea.) Plastic Transfer Pipet (1 ea.) Instruction Manual (1 ea.) Features Largest Sharpest Display Scale Available Exclusive Zero-Ring Requires No Calibration Tools Durable, All-Metal Design 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. All units feature rubber grips on the body, which block the transmission of hand heat to reduce temperature errors. Compact Portable. The small size of the X-Series models allows them to be used anywhere the field, plant, or lab. 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. Wide Selection of Scales Ranges. Choose from Brix, Salinity, Refractive Index (nD), and Coolant (freezing points of Ethylene Propylene Glycol, Battery Charge Level). Automa

Retrieved from Dr. Hanneman's vault !!! - the famous Diamond Eye Reflectivity Meter. Dating to the 1970's, when the simulant known as Cubic Zirconia was introduced, this was among the the original "Diamond Testers" before thermal conductivity probes came on the market. But the Diamond Eye still has relevance and purpose today, re-configured by Dr. Hanneman as a Relative Reflectivity Meter, using the Auxilliary Scale (see photo), along with his customized testing method. Just calibrate the meter with a reference gem of your choosing (Spinel, in this example), where the needle on the meter points to the bold, vertical hash line at the center of the scale. Now measure an unknown gem, and note the relative needle position. If it points to the left of the Spinel reference mark, then your unknown gem has a reflectivity value (and refractive index) less than Spinel. Or, if the needle points higher up the scale than the Spinel reference position, then your gem has a greater reflective and refractive index value than Spinel. To further narrow down the identity of your unknown gem, you can establish other reference ponts along the auxilliary scale using a low reflective gem such as Quartz (well to the left of your Spinel mark), along with a high reflective gem such as CZ (well to the right end of the scale). The main photo of the Diamond Eye shows the rotary Calibration knob at the left, the Gemstone Platform at the lower center, surrounding the Optical Eye, and the red Test button at the right. To measure a gem, just center it, table facet down, over the Optical Eye, then shield out ambient light with the included Light Shield, and then press the red Test button, which triggers the movement of the needle up to its relative Reflectivity value.
