Manufacturer: Atago Brand: Atago Model: ATA-2931

The Atago 2931 MASTER-BC is a handheld, portable refractometer that has dual-scale measurement of ethylene glycol (EG) 0 to 70% [0 to -50 degrees Celsius (C)], and propylene glycol (PG) 0 to 70% (0 to -50 degrees C), has manual temperature compensation, and is housed in a plastic body. A refractometer measures the refractive index of a solution in a sample, converts it to substance concentration in units of percent by weight, and displays the results. Handheld 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 polybutylene terephthalate (PBT) plastic body for use with salty and acidic samples. Its ridged outer shell has a telescope-shaped, streamlined design, and a spoon-shaped tip for smooth sampling. The outer shell grip is ridged for gripping, and easy to clean, which reduces the possibility of food and sample entrapment, avoiding contamination and bacterial growth. The 2931 MASTER-BC features manual temperature compensation. 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. The unit is water-resistant. Ambient light illuminates the scale, and no additional power source is required. The analog salinity 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. Specifications Measurement scale ranges freezing temperature of 0 to -50 degrees C (EG), and 0 to -50 degrees C (PG); 1.150 to 1.300 battery fluid d20/20 Minimum detection scales freezing temperature of 5 degrees C (EG), and 5 degrees C (PG); 0.01 battery fluid d20/20 Sample volume 10μl or more Illumination Am...

The VEE GEE BX-10 is a handheld, portable, water-resistant sugar refractometer with a Brix scale that measures in the 0.0 to 10.0% range, is powered by ambient light, has manual temperature compensation, an optical glass prism, and a durable metal body with rubber grip. 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. Handheld 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 metal body. The VEE GEE BX-10 features manual temperature compensation with an ambient temperature of 10 to 30 degrees C. The unit is factory-calibrated and can be calibrated with distilled water. Calibration can be controlled and adjusted with a tool-free calibration ring and a set screw. The outer shell is rubber coated with dimpled grip for easy gripping and the rubber coating guards against hand heat for accurate measurements. A non-roll stand prevents the unit from rolling when placed on a flat surface such as a table or bench top. The optical glass prism is mounted in an all-metal housing composed of copper alloy with a nickel-chrome coating for quick temperature equilibrium between the sample and the prism. The analog Brix scale features a bright, high-contrast display for clear visibility of the boundary and memory lines intersection. Instantaneous sample readings illuminated by ambient light are viewed through a monocular, focusable, cushioned eyepiece. The unit comes with a zippered vinyl carrying case, a plastic transfer pipet and an instruction manual.

Manufacturer: ATAGO U.S.A.,Inc. Brand: Atago Model: 2323

The Atago 2323 MASTER-2M is a hand-held, portable, water-resistant refractometer with a Brix scale that measures in the 28.0 - 62.0% range, has a spoon-shaped tip for automatic smooth sampling (ASD), has manual temperature compensation, and an Ingress-Protected (IP)-65 rated 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 aluminum metal body for heat and organic solvent resistance. The 2323 MASTER-2M 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 the ASD feature, 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.

Brix refractometers show the concentration of the soluble solids content (total solids) of a water-based solution. The soluble solids content is the total of all the solids dissolved in the water such as sugar, salts, proteins, and acids. The measurement reading value is the sum total. These refractometers are an excellent choice for testing fruit juices, beverages, jams, jellies and syrups. Also very useful for wineries, breweries, fruit harvesting, and food canning/packaging. An ideal choice for testing in conditions with large ambient temperature fluctuations. What's Included: Transfer pipet and carrying case. Food and beverage testing Largest display available Durable, all-metal design

Refractometer - Clinical Refractometer measures urine specific gravity, or gives the refractive index in seconds. Dimensions Place a drop or two of a sample on the prism and read the results. Sper Scientific portable refractometers work in ambient light with no battery or other power source necessary. A refractometer measures the extent to which light is bent (refracted) through a liquid sample. They are commonly used to help identify or confirm the identity of a sample, assess the purity of a sample, or determine the concentration of a solute in a solution. They can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two of a sample on the prism and read the results immediately. With reasonable care, their reliability, precision, and optical performance will last forever.

Fahrenheit MISCO 7084VP+ analog refractometer for testing ethylene glycol freezing point, propylene glycol freeze point, and the state of charge in lead-acid batteries. Test antifreeze, engine coolants, and heat-transfer fluids. The bright easy to read scale provides direct readings of propylene glycol freeze point as low as -60°F and ethylene glycol as low as -84°F. Automatic temperature compensation provides immediate, accurate, direct readings without the need to measure temperature or apply a correction. ONLY MISCO Refractometers come equipped with the patented ViewPoint Illuminator. ViewPoint is a light source with a self-contained power supply that provides extra illumination for the scale inside the instrument, improving the contrast and accuracy of the reading. Automatic-temperature-compensation eliminates the need for measuring temperatures and applying a correction factor, when taking readings. Both the range and response time of the temperature compensation are unsurpassed by any other instruments in the industry. Instruments without temperature compensation simply can't measure up. All MISCO Refractometers are calibrated at two points on the scale. Two-point calibration make this the most accurate hand-held refractometer available.
