About Atago 2351 MASTER-53 (Alpha) Hand-Held
The Atago 2351 MASTER-53α (alpha) is a hand-held, portable, water-resistant refractometer with a Brix scale that measures in the 0.0 to 53.0% range, has automatic temperature compensation (ATC), and is housed in an Ingress-Protection (IP)-65 rated metal body. A Brix refractometer measures the refractive index of a solution in a sample, converts it to sugar concentration in units of percent by weight (% Brix, also known as degrees Brix), and displays the results. Hand-held 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, die-cast metal body for heat and organic solvent resistance. Its body is IP-65 rated (excluding the eyepiece) for protection against dust and water jets, and the unit can be cleaned with running water under a faucet. The 2351 MASTER-53α features ATC for immediate, accurate readings, regardless of ambient temperature. Calibration can be controlled and adjusted with an exposed calibration screw and an included specialized screwdriver, although other items can be used to unscrew the unit. However, the unit retains its water-resistance. A spoon-shaped tip allows for automatic sample distribution (ASD) across the prism and boundary line (also called measurement line) for accurate, smooth sampling with small portions. The outer shell grip is smooth and easy to clean, which reduces the possibility of food and sample entrapment, avoiding contamination and bacterial growth. The analog Brix scale features a bright, high-contrast display for clear visibility of the boundary and memory lines intersection. Samples are viewed through a monocular, focusable, cushioned eyepiece. The unit includes a protective plastic storage case with a foam cut-out insert to cushion the instrument.

Refractometers are used to determine substance content in a sample, to provide unit readings of substances including Brix, salinity, and alcohol; to detect chemical impurities, or to measure components of samples such as industrial fluid. Refractometers measure the refractive index of a substance, which is its optical characteristic, and the number of dissolved particles in it. The refractive index is the ratio of the speed of light in empty space to the speed of light in a substance; when light passes from one medium to another. Generally, a low concentration sample has a larger angle of refraction than a high concentration sample. For example, a straw placed in a high-concentration substance appears more bent than when placed in a low-concentration substance. Refractometers can work with natural light, or with an external power source such as batteries or electricity. They typically have either a digital or analog reading display, though some units utilize both types. Some analog-display refractometers can be used for both solids and liquids. Digital-display refractometers are used exclusively for liquids. Types of refractometers include hand-held, benchtop, and in-process. Hand-held refractometers are elongated and telescope-shaped, or shorter and rectangular. Analog hand-held refractometer readings are obtained
