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.

Atago Co., Ltd. manufactures analytical instruments such as refractometers, polarimeters, and saccharimeters, as well as a variety of meters. The company, founded in 1940 and headquartered in Tokyo, offers products that comply with Hazard Analysis and Critical Control Points (HACCP), Good Manufacturing Practices (GMP), and Good Laboratory Practices (GLP) system standards, and many International Organization for Standardization (ISO) standards.

Have a look at Best Ben And Jerry’s.

Robinair's No. 75240 Coolant and Battery Refractometer is designed for use in measuring the freeze point of propylene or ethylene glycol based cooling systems and for checking the strength of electrolyte solution batteries. This precision instrument features high-quality optics with ultra smooth focusing. Scale range: -60 degrees Fahrenheit to +32 Fahrenheit. This handheld refractometer is a portable, precision optical instrument used for measuring the freeze point of engine coolant and the operating state of battery charging liquid. It is used on transportation vehicles, such as cars, tractors, tanks, ships, etc., which use propylene or ethylene glycol for coolant and sulphuric acid for charging liquid. When a liquid (such as coolant or charging liquid) is placed on the prism, the light passing through it is bent. The more concentrated the liquid, the more the light will bend. The refractometer contains a reticle, or scale, that is enlarged through the eyepiece to measure this bent light. The values of the scale have been established to evaluate the coolant or charging liquid. Complete kit includes refractometer with rugged aluminum housing, eyedropper, screwdriver, vial of distilled water, cleaning cloth, foam lined rigid plastic case, and complete usage instructions. Robinair, a Bosch Automotive Service Solutions brand, is a global leader in service tools and equipment based in Owatonna, Minnesota. Robinair is recognized throughout the world as the quality and performance leader in AC/R evacuation tools and this position has led to its success with the full range of products that serve the heating/ventilating/air conditioning/refrigeration (HVAC-R) and mobile markets, which includes the automotive aftermarket along with other industries such as agriculture and construction.
