The VEE GEE STX-3 is a handheld, portable, water-resistant salinity refractometer that measures salt concentration in parts per thousand (PPT) in the 0 to 100% range and specific gravity (SG) of seawater in the 1.000 to 1.070 range, has automatic temperature compensation (ATC), and a durable metal body with rubber grip. A salinity refractometer measures the concentration of salt, such as sodium chloride, magnesium and calcium sulfates, in liquids and displays the results. Handheld refractometers, also known as sugar meters, concentration meters, or Brix meters, are commonly used in the culinary, food and beverage, pharmaceutical, educational, geological, chemical, and ecological industries, and for water-testing applications.

This refractometer is housed in a durable metal body. The VEE GEE STX-3 features ATC for immediate, accurate readings, with an ambient temperature of 10 to 30 degrees C. The unit is factory-calibrated and can be calibrated with distilled water. Calibration can be controlled and adjusted with a tool-free calibration ring and a set screw. The outer shell is rubber coated with dimpled grip for easy gripping and the rubber coating guards against hand heat for accurate measurements. A non-roll stand prevents the unit from rolling when placed on a flat surface such as a table or bench top. The optical glass prism is mounted in an all-metal housing composed of copper alloy with a nickel-chrome coating for quick temperature equilibrium between the sample and the prism. The analog Brix scale features a bright, high-contrast display for clear visibility of the boundary and memory lines intersection. Instantaneous sample readings illuminated by ambient light are viewed through a monocular, focusable, cushioned eyepiece.
