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.

Use these economical refractometers to take quick and easy measurements. Refractometers feature adjustable focus and a zero adjustment screw for calibration. Each refractometer is calibrated and adjusted to read at 68°>F (20°>C). Models with automatic temperature compensation (ATC) are ideal for applications where the temperatures of your samples vary. Refractometers are made of corrosion-resistant brass and have rubber-insulated grips. Include hard case, calibration screwdriver, and instructions. Shpg wt 1 lb (0.5 kg). Brix Refractometers measure soluble solid concentration of sugars, salts, proteins, and more in foods and liquids-ideal for quality control and R & D applications. Use to measure % Brix of juices,beverages, and other sugar-based liquids. Salt Refractometers measure salt content in parts per thousand (ppt) and specific gravity or % salinity, depending on model. Use to measure salt concentration of water or brine.

Manufacturer: ATAGO U.S.A.,Inc. Brand: Atago Model: 2374

The Atago 2374 MASTER-93H is a hand-held, portable refractometer with a Brix scale that measures in the 45.0 - 93.0% range, has heat- and water-resistance, and corrosion-resistant tempered glass, an Ingress-Protection (IP)-65 rating, and automatic temperature compensation (ATC). 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 body is Ingress-Protection (IP)-65 rated for durability, and protection against dust and water jets. The 2374 MASTER-93H features a corrosion-resistant, tempered glass prism for extended life. It has automatic temperature compensation (ATC) for immediate, accurate calibration readings, regardless of ambient temperature, 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. Ambient light illuminates the scale; no additional power is required. 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.

The Gemological refractometer is considered by many to be the most important of all gem testing instruments. The primary use of the refractometer is to measure the angle at which light traveling through the stone is bent or refracted. This is called Refractive Index (R.I.). As Refractive Index is usually different for different gemstones, this provides an important clue for accurate gemstone identification. Gemological refractometer also can be used to determine whether or not a stone is single or double refracting. For doubly refracting stone, based on the difference between 2 readings you obtain from the refractometer, strength of the gemstone's double refraction (birefringence) may be computed and it offers an important gem identification aid, as it differs from gem to gem. Also refractometer is one of the few instruments capable to give you information for opaque stones as well as transparent stones. Quality of the instrument is important to enable you to perform consistent and reliable test for years to come. Our refractometer has all metal construction with built-in light (no flashlight or any other light source required) and polarizing filter, allowing you to perform all needed tests, it comes with vinyl soft case with belt loop for convenience while traveling and hard case for safe storage. Features: All metal quality construction Built-in LED light source with 3 x 1.5v batteries - included Accuracy: 0.01 Measurement range: 1.30 - 1.81 Polarizing Filter Weight: 0.9 lb Application: Gemology Hard and soft cases are included R.I. liquid is not included, please purchase certified R.I. oil from reputable sources. Please be aware that R.I. liquid is not included.
