Product Description

The Atago 2343 MASTER-4M is a hand-held, portable refractometer with a Brix scale that measures in the 45.0 - 82.0% range, has a spoon-shaped tip for automatic smooth sampling (ASD), manual temperature compensation, and a ridged outer shell. 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 aluminum metal body for heat and organic solvent resistance. The 2343 MASTER-4M features manual temperature compensation. The unit can be calibrated with water. 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, and sample disposal from the edge. With ASD, the daylight plate does not need to be lifted to cover the prism with the sample. 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 by looking through the monocular eyepiece and viewing where the boundary line intersects with the memory line. Digital hand-held models provide a digital readout. Benchtop refractometers typically measure with a higher degree of accuracy than hand-held 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.

Verified Purchase
I purchased this refractometer for something that needs to be tested as it is cooking to gage when it is finished. I put the product on the end well and would let it cool for up to 5 minutes before running it down the shaft and closing the lid to read. It would give a confusing read. I would then open the lid and wave it around to ensure it was cool and read it again, I thought I was getting an accurate reading but after canning, the next day I looked at the end result, it was like water, nothing like the thick syrup I was looking for. We tried to set the sample in front of a fan and still got a bad reading. Then we placed the sample in a metal cup on a bed of ice, We read that sample and it was spot on. If you are not in the position to have ice on hand to get an accurate reading, I would not reccommend this instrument. Not worth the money. I had a cheaper one that read better with less hassle, but that was lost in a move, unfortunately.
