About Atago 3405 PR-32a Palette Series Portable Digital
The Atago 3405 PR-32α Palette is a digital refractometer that measures low Brix (0.0 to 32.0%) concentration of liquid samples with high measurement accuracy at + or - 0.1% Brix, automatic temperature compensation (ATC), a user-scale function, and external light interference (ELI). 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. Refractometers are commonly used in the optical, chemical, geological, ecological, culinary, food and beverage, pharmaceutical, and educational industries, and for water-testing applications.This refractometer features a user-scale function to input the coefficient into a formula (concentration = Brix X coefficient), and display concentrations of each type of sample. Programmable user scales enable control of various liquid concentrations. The unit has a digital, LED-illuminated display of % Brix, or temperature in degrees C. It has external light interference (ELI) technology for accurate measurement near windows or outdoors. The unit requires one drop of sample, and provides measurement results in three seconds, in a sample measurement temperature range of 5 to 40 degrees C. It has ATC for accuracy, and can be calibrated with distilled water. The unit’s sample well is made of stainless steel 316 for durability. Power source is a 9V battery (included). The 3405 PR-32α has Ingress Protection (IP)-64 for protection against dust and liquids, and meets International Organization for Standardization (ISO) 9001 standard for accuracy.Specifications Measurement scale range 0.0 to 32.0% Brix Minimum detection scale 0.1% Brix Accuracy + or - 0.1% Brix Sample measurement temperature range 5 to 40 degrees C (ATC) Ambient temperature 5 to 40 degrees C Light source and display type LED digital, % Brix, or degrees C Light source and display type LED digital, degrees C Power source 9V battery (included) Standards met Ingress Protection (IP)-65; ISO 9001 Dimensions 4 x 17 × 9cm (H x W x D) Weight 300g 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 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 handheld, benchtop, and in-process. Handheld refractometers are elongated and telescope-shaped, or shorter and rectangular. Analog handheld refractometer readings are obtained by looking through the monocular eyepiece and viewing where the boundary line intersects with the memory line. Digital handheld models provide a digital readout. Benchtop refractometers typically measure with a higher degree of accuracy than handheld units. In-process refractometers are used for continuous process monitoring and data readouts, and are generally fitted into a piping system for ongoing analysis. Refractom
