They typically have either a digital or analog reading display, though some units utilize both types. A sample is measured by dipping, touching, or stirring the tip into the sample. The Atago 3741 PEN-Wrestling is a handheld, pen-shaped, digital refractometer that measures urine specific gravity (SG) in a 1.0000 to 1.0600 range, has external light interference (ELI) warning, automatic temperature compensation (ATC), and is commonly used by athletes. This refractometer has a compact, ergonomic, pen-shaped body (16 x 3.8 x 1.8cm), with a thin prism head for one-handed operation, and two measurement process options. Generally, a low concentration sample has a larger angle of refraction than a high concentration sample. Handheld, digital, clinical refractometer for urine specific gravity (SG) measurement in a 1.0000 to 1.0600 range to determine hydration levels of athletes during events such as wrestling 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. Specifications Measurement scale range Urine specific gravity (SG), 1.0000 to 1.0600 Measurement resolution Urine SG 0.0001 Measurement accuracy Urine SG + or - 0.0010 Sample measurement temperature 10 to 40 degrees C (ATC) Ambient temperature 10 to 40 degrees C Measurement time 2 seconds Display Digital, LCD Power supply Included AAA alkaline battery (1) Dimensions 16 x 3.8 x 1.8 cm (H x W x D) Weight 70g H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. Refractometers can work with natural light, or with an external power source such as batteries or electricity. The unit has automatic temperature compensation (ATC) for immediate, accurate calibration readings, regardless of ambient temperature, and can be calibrated with water. External light interference (ELI) feature displays warning message when direct light is detected Antigo Refractometer Images High Quality Resolution A refractometer measures the refractive index of a liquid or solid in a sample, converts it to concentration in units of percent by weight, and displays the results. 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. For example, a straw placed in a high-concentration substance appears more bent than when placed in a low-concentration substance. manufactures analytical instruments such as refractometers, polarimeters, and saccharimeters, as well as a variety of meters. Refractometers measure the refractive index of a substance, which is its optical characteristic, and the number of dissolved particles in it. Lab Refractometers ATAGO Digital Hand-held Dried Fruit Moisture Meter PEN-Dried Fruit Digital Refractometer Some analog-display refractometers can be used for both solids and liquids. Determine acceptable hydration levels by using this digital urine S.G. refractometer, which offers accurate, worry-free testing of urine specific gravity. Show More... Ergonomic, pen-shaped body (16 x 3.8 x 1.8cm), thin prism head for one-handed operation, with two measurement process options Refractometers are commonly used in the optical, chemical, geological, ecological, culinary, food and beverage, pharmaceutical, and educational industries, and for water-testing applications. An external light interference (ELI) feature displays a warning message when direct light is detected. Body has Ingress Protection (IP)-65 rating for protection against dust and low pressure water, and prism head has IP-67 rating for protection against dust and liquid immersion, for ease of cleaning Types of refractometers include handheld, benchtop, and in-process. Element 04DCWTELPPQuadrant 7.75 - Skate Decks This device comes with a strap holder, and plastic protective carrying case that snaps closed. Analog handheld refractometer readings are obtained by looking through the monocular eyepiece and viewing where the boundary line intersects with the memory line.
