The Atago 2340 HSR-500 is a hand-held, portable refractometer with a Brix scale that measures in the 0.0 to 90.0% range, a high-contrast transmission system, and a 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 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 2340 HSR-500 features a transmitting system that provides a high-contrast field of view. The unit has manual temperature compensation, and 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. 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.
What’s in the Box?
This nine-piece set of Stainless cookware consists of a 10-inch fry pan with a layer of scratch-resistant, professional-grade nonstick coating bonded to the interior steel layer; a 2-quart covered saucepan; a 3-quart covered saucepan; a 3-quart covered sauté pan; and a 6-quart covered stockpot. Polished 18/10 stainless-steel pan and lid handles are riveted for strength and grooved on the top for comfort. Both the lids' handles and the pans' long handles (holed for hanging on hooks or pegs) stay cool on the stovetop but won't be harmed by an oven's highest heat, although the nonstick pan should not be in an oven hotter than 400 degrees F. This Stainless cookware is dishwasher-safe, but hand washing is recommended, and it's essential for the nonstick pan. --Fred Brack

All-Clad Stainless Construction
Each piece of All-Clad cookware features a unique metal bonding construction. All-Clad Stainless cookware sandwiches a thick core of three separate layers of aluminum between an easy-to-clean, highly polished 18/10 stainless-steel cooking surface and a magnetic stainless-steel exterior. The aluminum core retains heat and evenly distributes it along the bottom and up the sidewalls of the cookware. The stainless interior is stick-resistant and cleans easily. The magnetic stainless-steel exterior gives the cookware a gleaming finish. All-Clad Stainless also features the company’s signature "stay-cool" long handles, lids fashioned from gleaming 18/10 stainless steel, and highly durable stainless-steel rivets. All-Clad Stainless cookware is one of five collections from All-Clad Metalcrafters. Designed to work on conventional gas and electric ranges, as well as induction cooktops, All-Clad Stainless cookware is the best-selling collection in a full line that includes All-Clad LTD, Cop-R-Chef, Master Chef 2, and Copper Core.
Features and Benefits
All-Clad pans with a stainless interior cooking surface are oven-safe up to 500 degrees. All-Clad pans with a non-stick cooking surface are oven-safe up to 400 degrees, but should not be used under the broiler. We recommend using a low to medium temperature when cooking with All-Clad. Higher heats are not necessary and may cause discoloration (see cleaning instructions below). Other features include:
Warranty
From date of purchase, All-Clad guarantees to repair or replace any item found defective in material, construction or workmanship under normal use and following care instructions. This excludes damage from misuse or abuse. Minor imperfections and slight color variations are normal.
Cleaning Instructions
For daily cleaning, warm soapy water is sufficient. Clean your All-Clad thoroughly after each use. Food films left of the pan may cause discoloration and sticking. To get rid of stuck-on food or discoloration and stains from using too high of a heat, we recommend cleaning your All-Clad with a product called Bar Keeper’s Friend. To use the Bar Keeper’s Friend, simply use a soft cloth or sponge and water and make into a soupy paste. This can be used on the interior, as well as the exterior of your All-Clad (excluding the Cop-R-Chef). The Bar Keeper’s Friend can also be used on the exterior of the All-Clad Stainless collection, LTD collection, and MC2 collection. For cleaning of the Cop-R-Chef exterior, simply use a brass/copper cleaner. If your water has a high iron content, you may notice a rusty discoloration. Use Bar Keeper’s Friend to remove it.
