VEE GEE® BX-4 Handheld Refractometer

Exceptionally simple to operate and provides quick, accurate measurements for the concentration of nearly any aqueous solution. Operation consists of placing one or two drops of sample on the prism, closing the daylight plate over the sample, then looking through the focusable, cushioned-rubber eyepiece for the readings. Features the largest, easiest-to-read scale available with clear, sharp figures, screen shading, and incredible contrast. Features rubber grips on the body that block transmission of hand heat to reduce temperature errors. The small, compact size makes it portable so it can be used anywhere the field, plant, or lab. 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. Rugged, all-metal construction provides years of reliable use. Non-roll stand ensures that unit won’t be prone to roll off the surface. Scale: Brix. Range: 45-82%. Resolution: 0.2%. Accuracy: ± 0.2%.
