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

The VEE GEE NDX-2 is a handheld, portable, water-resistant refractometer for refractive index measurement of oils in the 1.425 to 1.520nD range, is powered by ambient light, has manual temperature compensation, an optical glass prism, and a durable metal body with rubber grip. 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 NDX-2 features manual temperature compensation with an ambient temperature of 10 to 30 degrees C. The unit is factory-calibrated and can be calibrated with a liquid standard. 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. The unit comes with a zippered vinyl carrying case, a plastic transfer pipet and an instruction manual.

A portable meter is commonly used to measure the pH of substance such as food, beer, or wine, and is also used to test cleaning water, rinse water, and wastewater in chemical, industrial, and food applications. This microprocessor-based meter has Automatic Temperature Compensation (ATC) for accurate readings in fluctuating temperatures, and three-point, push-button calibration with auto-buffer recognition of US and National Institute of Standards and Technology (NIST) standards for a wide range of results. The meter’s waterproof and dustproof housing has Ingress Protection (IP) 67-rating for protection against solid objects or liquids. It has a large, upright, dual-line LCD screen for ease of viewing, error messages, a hold function which freezes readings for recording, and an auto shut-off that turns the meter off after 8.5 minutes of nonuse to extend the life of the batteries. A protective cap reduces contamination, and a double silicone O-ring eases electrode module replacement.

Brix refractometers show the concentration of the soluble solids content (total solids) of a water-based solution. The soluble solids content is the total of all the solids dissolved in the water such as sugar, salts, proteins, and acids. The measurement reading value is the sum total. These refractometers are an excellent choice for testing fruit juices, beverages, jams, jellies and syrups. Also very useful for wineries, breweries, fruit harvesting, and food canning/packaging. An ideal choice for testing in conditions with large ambient temperature fluctuations. What's Included: Transfer pipet and carrying case.
