The Atago 1310 DR-A1 is a benchtop Abbe refractometer for refractive index measurement (1.3000 to 1.7100nD) and Brix (0.0 to 95.0%) scale of liquid and solid samples such as glass, plastic, lenses, rubber, solid films, and food and beverages with a 5 to 50 degrees C temperature range, has an LCD digital display of measurement readings, and an analog display of the boundary line. A refractometer measures the refractive index of a liquid or solid in a sample, converts it to concentration in units of percent by weight, and displays the results. 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. Refractometers are commonly used in the optical, chemical, geological, ecological, culinary, food and beverage, pharmaceutical, and educational industries, and for water-testing applications.
This refractometer has an Abbe condenser to enhance resolution. The Atago 1310 DR-A1 refractometer is housed in a durable, die-cast aluminum metal body for resistance to heat and organic solvents. It can be connected to a circulating constant temperature bath (sold separately) for specimen temperature control. A digital LCD displays the measurement reading and a monocular, focusable, cushioned eyepiece provides for cross-hair boundary line setting. The analog scale is orange and gray with a high-contrast display for clear visibility of the boundary (measurement) and memory intersection lines, and has a cross-hair refraction view for measurement. An adjustable knob provides color (boundary) alignment. The Atago 1310 DR-A1 model can be calibrated with distilled water. The instrument has a 6-foot power cord and complies with American Society for Testing and Materials (ASTM) standards. It also comes with ten plastic tube bands, which work like zip ties to tighten the tubes for water temperature control of the water bath. In addition, the unit comes with an AC adaptor, an AC power cable, a test piece with refractive index of 1.51 to practice solid sample measurement, a 4 ml bottle of monobromnaphthalene as contact liquid for solid sample measurement, an Allen wrench for prism replacement, a light adaptor to reflect light for solid sample measurement, a test report, and an instruction manual.

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 handheld, benchtop, and in-process. Handheld refractometers are elongated and telescope-shaped, or shorter and rectangular. Analog handheld refractometer readings are obtained by looking through the monocular eyepiece and viewing where the boundary line intersects with the memory line. Digital handheld models provide a digital readout. Benchtop refractometers typically measure with a higher degree of accuracy than handheld units. In-process refractometers are used for continuous process monitoring and data readouts, and are generally fitted into a piping system for ongoing analysis. Refractometers are used in a wide variety of applications in the culinary, food and beverage, pharmaceutical, educational, geological, chemical, ecological, and automotive industries, and for water-testing applications.
