HAND HELD REFRACTOMETERS
Easy to Use! Place 1 or 2 drops of sample on the prism, closing the daylight plate over the sample, then look through the focusable, cushioned, rubber eyepiece for the reading.
Accurate! Features 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.
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 features non-roll stands for safely placing the unit on on bench or tabletop without rolling off.
Compact and portable! The small size of the X-Series models allows them to be used anywhere...the field, the plant, or the lab.
Tool-free calibration! The Vee Gee exclusive, patent pending "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 zero or the correct value of the liquid, than secure the set screw.
Wide Selection of Scales and Ranges! Choose from Brix, Salinity, Refractive Index (nD), and Coolant (freezing points of ethylene & propylene glycol, battery charge level). Model CXL-1 comes with 3 scales for testing urine specific gravity, plasma/serum protein, and refractive index.
Automatic Temperature Compensation! (ATC) Models BTX-1, BTX-20, STX-3, CTX-1 & CTX-2 feature ATC, which frees the user from having to re-calibrate in work environments with large temperature swings. The effective compensation range is 10-30º C.
PORTABLE DIGITAL REFRACTOMETERS
Easy to use! Place 1 or 2 drops of sample on the prism, press the READ/ENTER key, and within a few seconds the reading is shown on the large LCD display.
Easy calibration! Simply use distilled water and push the ZERO/CALIBRATE button. Oil standards are not required for calibration.
Automatic! The LED light source detects the refractive index of the sample, the thermo-sensor detects current prism temperature, and the result displays.
Features! Top-Level Palmtop Design, High Accuracy and Wide Ranges, Brix and Refractive Index Scales.
