VEE GEE Scientific X-Series Handheld Refractometers are simple to operate and provide quick, accurate measurements for the concentration of nearly any aqueous solution.
Simply place 1 or 2 drops of sample on the prism, close the daylight plate, and look through the eyepiece for the readings. To calibrate, simply place a few drops of distilled water or liquid standard on the prism, turn the patented Zero-Ring until the boundary line between the blue and white areas is at the correct value, and secure the set screw.
Also feature all-metal housing for quick temperature equilibrium, non-roll stands, focus-able eyepiece, and rubber grips on the body to block hand heat.
Models BTX-1, BTX-20, and STX-3, features automatic temperature compensation (ATC) with a range of 10 to 30°C.
